If you dry them out and peel off the membrane from inside the eggshell, you can crush them into a fine powder and it should go much smoother. The bonus there is that you're getting rid of proteins and other contaminants in the membrane that can slip into the mixture.
Nile, I have just completed a repeat of your Calcium Acetate experiment. With a couple little changes to the procedure, I ended with just a little over 205g of semi dry product. Thanks again for the pointers in the video. The net result came out very clean with no visible signs of contaminants. Now just to find a suitable wash before the final drying process. With the lessons learned and this video, I think I have a good shot at a reasonably pure CaCl2. Previous attempts have not yielded well as you know. Keep ya posted. Great Job~! Rob
I would not recommend burning off the egg shells. In my experiments, it seems as though the calcium absorbs the contaminants during the burn off. Those extra contaminants are difficult to eliminate from the final product and also contributes to a foul odor during the reaction phase. However, if you have a means to use very high heat it may work but you will end up with CaO instead. Consider the following: 1-In about a 500ml of distilled water, boil the shells in broken down quarters. Let stand (to settle) and remove/filter out the floating and foamy material and try not to decant the shells into the filter. Save the water and repeat using the reclaimed water. 2- Reduce the shell size by another 25% boil, filter, and again don't decant the shells. Save the water. 3-In a grinder/blender ( I used a magic bullet ) decant the shells and about a cup of the filtered water from above into the container. Blend until the shells are reduced to "sand" like size. This step eliminates liberated Ca dust from entering the breathing environment. 4- Decant the entire milky and sandy product back into the beaker (or pot). With strong stirring add 10ml of Vinegar one drop at a time (to control reaction foaming) this step is to capture the Ca “milky dust” that would have otherwise be lost during filtering. 5- Filter the water leaving (sandy) shells behind. Save the water, and allow the water to cool. 6- Now rinse the remaining Ca "sand" with clean water (tap, distilled or RO), decanting and discarding anything that does not sink to the bottom. Repeat until rinse is clear. Then drain off all the water possible. Add back your filtered cooled (room temp) water from step 5 to your beaker/pot. 7-Perform the final reaction. Note: Foaming can be somewhat controlled with strong stirring plate and/or by the addition of the acid in controlled drops. I have also tried a spritz of spray non-stick or a drop of veg oil with good results. I have had my best results keeping the reaction in a CO2 environment. WARNING (do not allow reaction to compress CO2 and pressurize). Just in my experience, I believe that during the reaction the foam is responding to the outside air thus exacerbating foam production. In the CO2 environment, I have seen no more than ½” of foam at max. I bubble my reaction into a separate beaker of water and sodium bicarbonate solution. It is also serves as a good indicator when the reaction is complete or having an uncontrolled over reaction.
youre better off just buying a big giant sack of agricultural lime because it also has oher things like magnesium and trace metals but you get more...and...no hassle of making it....just DO NOT use hydrated lime
I would mention that the solution was colloidal because of leftover proteins and boiling it might push out and break apart the proteinsto form a white precipitate too :)
I've done this same reaction, with egg shells and vinegar. After the egg shells are good and dry, I put them in a blender and pulverize them. This avoids the "floating eggshells" problem, because they are a powder. Also, there is more surface area available to the vinegar, so I think it speeds up the reaction?
Egg shells are quite good source of CaCO3, but you really need them to be as clean as possible. Wouldn't it be easier to use chalk? (are there scools in other countries that still use chalkboards? 'cause in my country they are pretty much prevaling and I really don't know whether it's true to other countries) And I'd really like to see the Iodine clock reaction and making pyridine. Thanks for the great work, Nile.
+Lars Veldscholte (Compizfox) +Nile Red I'll check this. Thanks for pointing it out. (sadly, the government of my country doesn't really care about health or teachers...)
For those who are impatient, I've found putting the wet calcium acetate in the oven at just below boiling for 20 minutes is enough to dry it without burning it.
I was kinda surprised when you said that most kitchen vinegars are 5%, because at least in Hungary, most vinegars are either 10% or 20%, only things like apple cider vinegars and other natural vinegars are 5% here.
Cheapest source for Calcium carbonate seems to be "Garden Lime". You can buy it in a large 20kg bag. Garden lime is basically just slightly dirty Calcium Carbonate. Would definitely be cheaper than buying that many eggs, and definitely cheaper than buying the anti-reflux medds.
if you grow your own tobacco and extract nicotine from green leaves. you can extract more. anyway it is for chemistry not for making money. I dont even smoke. it would only be cool how it'S doable
Would heating the solution maybe help to speed up the reaction at the beginning? Also is it possible that the couldiness when boiling the filtered solution is due to the decomposition of calcium bicarbonate that formed because of all the CO2 and excess of calciumcarbonate? When you heat calciumbicarbonate in aqueous solution it turns into calciumcarbonate and drops out.
If using eggshells or another organic source of CaCO3, like bonemeal or bones, or seashells, I suggest roasting the shells at high temperature for a longish time to burn off any organic material. This should probably be done outside one a grill since i'm sure the smell would be atrocious! I'd imagine a blowtorch would work as well. For those looking for a pure form of CaCO3, might I suggest chalk sticks? Like the kind teachers use. A box is around 49 cents and it's almost pure CaCO3 except for a snall amount of binding agent.
I would highly recommend adding backing soda to calcium acetate solution and then adding vinegar to the purified calcium carbonate because calcium carbonate can be easily cleaned since it doesn’t dissolve in water.
Eggshell will never be a pure source of calcium, as it consists of a protein matrix as well. You could try to calcine it away or use piranha solution, but it's way easier to use crushed limestone. Still not pure, but the impurities aren't organic. Also, 45% vinegar is available from Walmart and will make the evaporation step way faster, as would applying a vacuum.
to separate it from the Tums, you would have to crush them up and dissolve then in water, perhaps with a little baking soda as well, then filter out the calcium carbonate, since the sugar and other chemicals are mostly water soluble, and only the carbonate is really insoluble. then it would just be a matter of following the steps in the video here with that calcium carbonate. if the sugar doesn't want to separate from the carbonate for whatever reason, then dissolve it in the acid, and add baking soda to precipitate out calcium carbonate, then filter and wash the carbonate to get calcium carbonate by itself. then just do the process shown in this video to get the acetate.
I'm assuming the foaming is mostly CO2, for example using a flash with a hose nipple on the top and put a stopper in the top and then the foam exits through the line out and into another vessel.
In germany supermarkets have cheap (a buck/250ml) 25% concentratet foodgrade vinnegar. I used that with calciumhydroxide. Doesn't foam at all. The latter can be obtained at a building supply store, ask for lime and say you want to use real, pure slaked lime. They should understand. Reading thouigh doesn't hurt.
+SpektralJo So, if the chipped beaker is his mascot, then what would you call the melted and busted round-bottom flask? You know, the one from the Acetone synthesis? :)
I really like these videos about extracting things from natural sources, like the caffeine from tea/coffee ones. Not sure why, they just appeal. Not much of a chemist, but would you perhaps not have had more success using a large flat tray, like a pyrex baking dish? Seems like this would have reduced the amount of stirring required, by increasing the surface area of the floaty layer of eggshells.
Veerum Jokun put some vinegar and copper (be carefull with the penny because some have inside other over copper) add much of hidrogen peroxide and et voilà :D
Hey I am a big fan of all your videos, and i wanted to do a couple of your experiments. including this one. i started to make the calcium acetate from eggshells, which was kind of a pain. i didnt really consider the tums bc they are expensive for what they are and honestly it sounds messy. I keep chickens though; and, i feed them oyster shell to give them their calcium. oyster shell is available in large bags for just a few of dollars at most feed stores. it seems to me that this would be an better starting material for making calcium acetate because it is easier than eggshells and purer and cheaper than tums. anyway, just a thought. let me know what you think and good look too with your work. its been a lot of fun to watch all of your videos.
The yellow tint may be from the presence of sulfur. Burning the egg shells first should get rid of that. Just do it outside or in a fume hood, since it will produce sulfur dioxide... Or collect it and use it to make acid :)
You got some calcium acetate but about half of the white powder is something else. Let it recrystallize slowly, the calcium acetate crystals are fine, clear needle like crystals while the contaminant creates coli flower shaped accumulations of fine white crystals.(You can filter out the organic contaminants from the egg shells with Bentonite) I havent gotten more than 65% calcium acetate, even from pure calcium carbonate.
I can find calcite crystals in my area. Just some hunting around road cuts will find both calcite and gypsum crystals. I betyou can make calcium acetate out of either. The calcite crystals that I have gathered before are very clear. Maybe they are very pure?
I was a bit spooked when it precipitated out of solution, thought it was proteins from the egg coming out of solution and not the actual Calcium Acetate itself. Going to let my batch dry overnight. I'm planning to test the isolated stuff as part of a hydroponic fertilizer blend instead of just the ions in a solution.
Wouldn't it have been better to dry the eggshells, then grind them up using a mortar and pestle? Maybe they wouldn't have floated so much since it would be more like a powder.
of course - more surface area, reaction would have been shorter by a lot. except he probably didn't do that because it would have produced a lot more CO2 in that amount of time and possibly overflow his beakers.
+Nile Red Also, wouldn't there be a risk of calcination? Egg shells are pretty thin and easy to over heat. Or would that be the idea? To convert to the oxide and then to the hydroxide with the water in the vinegar? Then you would still get to the acetate I'd imagine.
Part of me wants to distill put the water before using it. You know, to save time. Though I wonder if the water is necessary to allow the dissolved eggshells somewhere to dissolve into.
You should invest $10.00 for a cheap electric coffee grinder. It really helps to powder many chemicals that would normally take quite a while with a mortar and pestle. Thanks and thumbs up.
What about refluxing eggshell powder with aqueous NaOH to get rid of (I hope) most of the amino acids and maybe some other stuff. Than separate the CaOH and react it with acetic acid to produce a higher purity product for the preparation of acetone.
kindly guide??? mean we should stir for 12 hours continuously or just soak crushed ground eggs in vinegar for 12 hours and after this just stir more... will it work or i will have to stir continously when it ends bubbling add more shell while stiring.
Is calcium acetate stable in air? It seems that it might be hygroscopic, and then would absorb carbon dioxide to reform calcium carbonate and a small amount of acetic acid. If you left a solution of calcium acetate exposed to air, would a precipitate of calcium carbonate form over time?
So, I repeated the experiment, but I used chalk instead of eggshells. There doesn't really seem to be much of a reaction between the chalk and the vinegar--except intermittent particles of chalk floating to the top. The vinegar I'm using is White Distilled Vinegar, with a 95% concentration. I diluted it because the number of chalks I would be using wouldn't fit the amount of vinegar that would come from the 95% solution. Quantitatively, I'm using 11.4 ml of Vinegar (the is the quantity before diluting it), and 11.4 grams of chalk.
chalk these days can contain any number of different substances. Yours could contain any ratio of calcium sulfate, calcium carbonate, and magnesium carbonate, perhaps not any calcium carbonate at all even!
Me too! I've been a Rush fan since he helped Bush stay in the white house...oh, you don't mean Rush Limbaugh? LOL, jk!!! I've been a Rush maniac ever since I got Permanent Waves for my 10th birthday and some of the best times of my life were accompanied by a Rush soundtrack :)
Are egg shells supposed to dissolve and disappear completely? For me looks would take years, or is the procedure completed when co2 stopped popping, even with shells still intact?
Hi Nilered, I remember watching one of your videos where you explained a phenomena where mixing two liquids having different boiling points made the overall boiling point increase in respect to the higher boiling point of the original liquids. I can't find it any more (I must admit I have watched all your videos so I dont know where to start... I remember it was around acetid acid or the likes but i just rewatched all I could find) can you help me here please?
I've been wondering, can you get in trouble for making nitroglycerin and other substances in very small batches just bc you enjoy the science of it and then destroy the compounds?
It depends on where you live. In most states/countries manufacturing explosives for any purpose is illegal without a special license, which is difficult to get. That being said, I'm pretty sure you can buy potassium chlorate (C-4) on Amazon by the pound, so some substances are less controlled than others. However nitroglycerin is so unstable and dangerous that it would be incredibly stupid to make unless you had a very good reason to make it, and a very clearly defined purpose.
If one were to increase the rate of the reaction by stirring this rapidly and harvest the foam head, what would the head consist of (chemically)? Calcium acetate?
We love your videos -- especially my daughter (4 yo). Quick question: What if instead of egg shells (CaCO3) you used Gypsum (CaSO4) against the acetic acid to produce the Calcium Acetate. Woops, that creates sulfuric acid, doesn't it? hahaha (I literally just learned that.) We have a ton of CaSO4 here left over from other work we did. Oh well, we'll give it a try. Best wishes!
The sulfate ion has a higher reactivity than an acetate ion. It would therefore form an unfavorable equilibrium so it likely wont work/wont work well. If heated high it might push it forward but as soon as you cool it down, then it will reverse. You could use cheap soda ash from the super market to react with the gypsum to make usable sodium carbonate. Since gypsum is rather insoluble, you might need to boil the soda ash with the gypsum for it to react.
I don't know if there's an equivalent tool in chemistry, but would something like a French Press have helped with your floating eggshells issues? You could have put them in, pressed it down just far enough so they're all submerged, and then also pressed it down the whole way as your filtering step (or at least a precursor to it if the mesh doesn't do as good of a job as the filter paper). Or would the material of the screen have contaminated your reaction?
+DeDraconis This French Press thing is also used for coffee right? If it is made out of steel or something like that then it may be dissolved by the Acetic acid (only slightly but you would get iron acetate in your product), if you would use plastic or any other material that can't be dissolved by acetic acid then it should be fine.
could you make a video of the jelly that you mentioned in the video? I think I actually made some calcium acetate, and I want to convert it into the jelly you mentioned in this movie.

You could freeze-concentrate the acetic acid to reduce the amount of water to be boiled off.
You can also make it from CaOH and Vinegar. A acid base reaction will take place that creates the Calcium Acetate.

Part of me wants to distill put the water before using it. You know, to save time. Though I wonder if the water is necessary to allow the dissolved eggshells somewhere to dissolve into.
A Q&A would be so cool
"and my vinegar is on the right" Adam Ragusea collaboration when?
You should invest $10.00 for a cheap electric coffee grinder. It really helps to powder many chemicals that would normally take quite a while with a mortar and pestle.
Thanks and thumbs up.
Amazing video quality! Did you get a new camera?
+JGPixl I got the Panasonic GH4 around christmas
If you were had the time could you just leave the filtered solution in a sunny place to evaporate? That would keep it from burning.
Would it be effective to use a blender?
I wonder how long you laid the Calcium acetate to dry and at what temp?
I wonder if heating the egg shells first would remove most of the impurities, if not just turning those impurities into carbon.
Would your reaction be faster if your ground your egg shells finer?
If you pulverize the eggshells first the reaction is done in minites
What about refluxing eggshell powder with aqueous NaOH to get rid of (I hope) most of the amino acids and maybe some other stuff. Than separate the CaOH and react it with acetic acid to produce a higher purity product for the preparation of acetone.
The membrane comes away quite easily if you put the shells in cold water as you use them. Just roll the membrane away.
I think it would probably be best to wash out the eggshells to get rid of the eggwhites. My attempt has turned into the meringue from hell.
Would you be wiling to do any experiments involving Uranium? Perhaps making Uranyl Nitrate?
+Anti Photon If only i could easily just get uranium. Also, radioactivity is scary!
+Nile Red Uranyl acetate is cheap from Ebay, when heated it decomposes into uranium oxides
Hello, in the manufacture of calcium carbide, is it possible to use any type of coal or exclusively coke? Thank you
Wanted to do this for camping where not allowed liquids but seems a bit a stretch camping at a festival 🤣
At the end you should read the names out at double or triple speed
+TheDessonater haha that would be pretty weird i think
kindly guide??? mean we should stir for 12 hours continuously or just soak crushed ground eggs in vinegar for 12 hours and after this just stir more... will it work or i will have to stir continously when it ends bubbling add more shell while stiring.
Does this work this lemon juice to make calcium citrate?
Is calcium acetate stable in air? It seems that it might be hygroscopic, and then would absorb carbon dioxide to reform calcium carbonate and a small amount of acetic acid. If you left a solution of calcium acetate exposed to air, would a precipitate of calcium carbonate form over time?
So, I repeated the experiment, but I used chalk instead of eggshells. There doesn't really seem to be much of a reaction between the chalk and the vinegar--except intermittent particles of chalk floating to the top. The vinegar I'm using is White Distilled Vinegar, with a 95% concentration. I diluted it because the number of chalks I would be using wouldn't fit the amount of vinegar that would come from the 95% solution. Quantitatively, I'm using 11.4 ml of Vinegar (the is the quantity before diluting it), and 11.4 grams of chalk.
chalk these days can contain any number of different substances. Yours could contain any ratio of calcium sulfate, calcium carbonate, and magnesium carbonate, perhaps not any calcium carbonate at all even!
That's what I found out. I just repeated the experiment
Can you make Calcium Acetate with limestone or calcite crystals? I can get both from natural sources in my area.
I used seashells, and instead of boiling, I added ethanol to try and get it to crash out of solution.
What about drying and pulverizing the eggshells?
You could ball mill the eggshell
What if you try to make cyanide from cherry pits
that would be so cool
+Sor Sor Science07
And such a bad idea as well.
It would be really cool but it seems like there would be some liability issues on his part.
+Rush Fan I love Rush
Me too! I've been a Rush fan since he helped Bush stay in the white house...oh, you don't mean Rush Limbaugh?
LOL, jk!!! I've been a Rush maniac ever since I got Permanent Waves for my 10th birthday and some of the best times of my life were accompanied by a Rush soundtrack :)
Isn't calcium acetate used to prevent high blood phosphate levels in patients who suffer from severe kidney disease?
Are egg shells supposed to dissolve and disappear completely? For me looks would take years, or is the procedure completed when co2 stopped popping, even with shells still intact?
I'm shocked that so much was left after the water evaporated. From a transparent liquid to that powder, thats crazy to me.
Please do a video on STRONTIUM ALUMINATE. PLEASEE :D haha
Hi Nilered, I remember watching one of your videos where you explained a phenomena where mixing two liquids having different boiling points made the overall boiling point increase in respect to the higher boiling point of the original liquids. I can't find it any more (I must admit I have watched all your videos so I dont know where to start... I remember it was around acetid acid or the likes but i just rewatched all I could find) can you help me here please?
It was a good video , we do have lots of egg shells
Do u have to sterilize the shells first , and pls give back the ratio of water to shells
Thank you
I would highly suggest using a larger container! 😂You should write that in capital letters onto your labs wall.
I've been wondering, can you get in trouble for making nitroglycerin and other substances in very small batches just bc you enjoy the science of it and then destroy the compounds?
It depends on where you live. In most states/countries manufacturing explosives for any purpose is illegal without a special license, which is difficult to get. That being said, I'm pretty sure you can buy potassium chlorate (C-4) on Amazon by the pound, so some substances are less controlled than others. However nitroglycerin is so unstable and dangerous that it would be incredibly stupid to make unless you had a very good reason to make it, and a very clearly defined purpose.
+dryuhyr the nitro was just an example. but keep up the videos, great fun to watch.

If one were to increase the rate of the reaction by stirring this rapidly and harvest the foam head, what would the head consist of (chemically)? Calcium acetate?
When would you do the flamming jelly and acetone vid?
+Saikit Tang I already filmed it, so it is just a matter of editing it
We love your videos -- especially my daughter (4 yo). Quick question: What if instead of egg shells (CaCO3) you used Gypsum (CaSO4) against the acetic acid to produce the Calcium Acetate. Woops, that creates sulfuric acid, doesn't it? hahaha (I literally just learned that.) We have a ton of CaSO4 here left over from other work we did. Oh well, we'll give it a try. Best wishes!
The sulfate ion has a higher reactivity than an acetate ion. It would therefore form an unfavorable equilibrium so it likely wont work/wont work well. If heated high it might push it forward but as soon as you cool it down, then it will reverse. You could use cheap soda ash from the super market to react with the gypsum to make usable sodium carbonate. Since gypsum is rather insoluble, you might need to boil the soda ash with the gypsum for it to react.
I don't know if there's an equivalent tool in chemistry, but would something like a French Press have helped with your floating eggshells issues? You could have put them in, pressed it down just far enough so they're all submerged, and then also pressed it down the whole way as your filtering step (or at least a precursor to it if the mesh doesn't do as good of a job as the filter paper).
Or would the material of the screen have contaminated your reaction?
+DeDraconis This French Press thing is also used for coffee right? If it is made out of steel or something like that then it may be dissolved by the Acetic acid (only slightly but you would get iron acetate in your product), if you would use plastic or any other material that can't be dissolved by acetic acid then it should be fine.
could you make a video of the jelly that you mentioned in the video? I think I actually made some calcium acetate, and I want to convert it into the jelly you mentioned in this movie.
+Jarom Schafer I posted that video yesterday! :)
Loving the new mic. What is it?
10% vinegar is 90 % water correct?
