taking chemistry lessons from teenages wow, shit you can do in 2019 on youtube is insane !
HAHA! Don't trust me completely! I was like 15 back then
Great video! I'm a young aspiring chemist as well and it's nice to see others with the same interests on RUclips!
+Lane Haden Thanks man! Love to see more kids interested in home chemistry!
Same man been loving chem since i was 14 great to see others out there like me
hey buddy, well done for your effort and motivation :)

Awesome, thank you!
Gerçekten harika videoların var
Dünyada hep senin gibi insanlar çok olsa
Teşekkür ederim siz bir harika ve kimya kahramanısınız
if you dont want to play with complex steps, you could just do molten separation, each oxide should have its own melting point
you know what, our ministry of education which known as MPM
want us to prepare silica gel from sand ,wth they are thinking!
韩信 hey! I’m an stpm student too 😂
Harith Syahmie r u here to search for the same thing too?
Same here😂
qiqi leng 1 more day before being scolded by teacher for doing nothing!!!!
we are here. together
surely in the formation step of silicic acid you could use HCl instead of H2SO4, and then wash out the former NaCl after drying. seems like a much cheaper approach, cause HCl is readily available. if the yield is reduced, just freeze the thing and let it crash out. or am I missing something
Good stuff, man! Using an alteration of your method with oxalic acid. I think im going to stop with the purified sand until I have a more proper set up to handle molten sodium hydroxide though lol.
Nice work bro. Thanks for the video. Really appreciate it!
No problem !
@@BackMacScican we take aluminium from sand because sand contain around 10% aluminium
I appreciate your effort sir!
question : can I use H2SO4 in the begging instead of HCl@@BackMacSci
"you mustn't react this in a glass crucible, only stainless steel"
*uses glass stir rod to stir it.
+AJ Pollard Haha ok you caught me on that one...
Glad you took that one good, I was afraid you wouldn't after I posted it.

AJ Pollard No, it is ok to stir it with glass, but just not in a glass container,
This is proof how inexperienced this kid is and things like thermite he shouldn't be doing. It's all fun until he builds a nuclear reactor in his back yard and it melts down.
Or worse.
U are an amazing youtuber and keep making such amazing videos people nowadays are not into these amazing videos that's why you don't have more. Views but people like me who go to college really need your videos thanks and sorry about that long comment
How to determine the percentage of pure silicon dioxide? Any formula?
Hopefully will get a quick reply
Park here for the formula too
haha
If you are curious about the purity of the final SiO2 in this video, it should be >99% as long as you fully convert the sodium silicate to SiO2. Good question, and I apologize that I'm shit at response time lol.
@@BackMacSci thank you for that
Is this just white sand?
You should refine this down to silicon, and then try upgrading the metallurgical grade silicon to electronic semiconductor grade silicon used in semiconductors.
Your way of going greener? Can you drive deeper into how you recover the silica from a mine? Lots of solar mining operations where this is?
Is it possible to turn siO2 into quartz crystal ?
Cool experiment. That is some pretty sharp thinking
Nice work.
Thumbs up'ed for the HCL/Beaker tip.
Can you make elementary si by heating it with coal ?
How is this turned to liquid silicone rubber?
This can also be done with table salt, also known as sodium chloride. The chain shouldn't be that much more complex.
Nice one! Would you consider silicon as a sustainable and environmentally friendly material?
I'm not too sure! I would have to do more research about its production. But this process is not too harmful to the environment!
Gonna have the coolest beach, in 'no-time'!
And most expensive
Hi, great video and very helpful info for what i'm attempting to do. I'm wanting to purify some beach sand in concentrated acetic acid (freeze distillation concentrated to somewhere around 30-40%), as i've read that it will dissolve the calcium carbonate and also iron and other metal impurities that should become iron acetate etc, which will be washed out afterwards when adjusting ph. So basically using a strong acetic acid instead of HCl. Then I will use the clean(ish) silicon beach sand to combine with sodium hydroxide and make sodium silicate as you did here - It will be for use as a binder in composites. Just one question... Did you heat the dry silicon sand with dry sodium hydroxide and it melted into water-glass like that? Or did you add some water before heating? Thanks!
Hi Kyle, sounds like you have a fun project planned. On the part of the procedure you’re referring to, I added no water to the mixture because it would prevent the NaOH from becoming molten. And we don’t want that because then the Sodium silicate will form very slowly. Thanks for checking out the video!
Hi, thanks for your reply! Ah, that makes sense - and the info i've been reading suggest that beach sand silica in particular is much slower in aqueous NaOH.
If you used 60 grams of your crude silicon dioxide with 80 grams of NaOH and the resulting yield of pure silicon dioxide was 40 grams after precipitating with the acid, does that mean that all 20 grams of the original crude 60 grams of silicon dioxide were impurities? Or did the acid precipitation step simply just not precipitate all of the silicon out of the sodium silicate mix?
I ask because I hope to just use the crude silicon dioxide without further purification and I thought (going by your results) that I may need to reduce the amount of NaOH a little bit, since it would mean excess NaOH in the sodium silicate mix?
Also, what is the least amount of water (in grams) that could be added to, say... 100 grams of the dry sodium silicate? I'm going for a dense yet workable sodium silicate mix, because when dry, the evaporated water will have left pores in it's place that will be throughout the set material, making it weaker.
I may also try adding 1-5% glycerin as a plasticizer when mixing in the water - i've heard glycerin and some other types of plasticizers can be used with silicates to increase plasticity slightly, so it's not so brittle.
Many thanks!
I think that the 20 grams of crude SiO2 that were not in the yield were left in the solution and didn’t precipitate, as you suggested. As for the amount of NaOH you are thinking of using, I would keep it the same but add more acid than I did. Finally, I do not know how to do the process of adding glycerin to the silicate so I can’t help you there, sorry! Have fun experimenting!
Thanks man, that's great! I won't be going to the precipitation stage, as I just want to make sodium silicate. And your video demonstrates how to make it from beach sand, plain and simple.
I'll test out what the effect of adding glycerin is and how much to use. It's for making semi-transparent greenhouse panes - sodium silicate will be worked into white cotton sheet, which should work much like fibreglass or something similar. It seems like it would be a great alternative to plastics (like poly-carbonate) as they all leach out toxic stuff into plants/soil/those who eat the contaminants. And glass is not an option, as earthquakes are very common here these days. I can even see potential for plasticized sodium/potassium silicate as a binder for adding to rough fibrous paper for making boats and other things. If that doesn't work, then there's a way to dissolve cellulose (pretreated in hot acid, then washed) using NaOH and Urea at cold temps around or below 0 degrees Celsius - it produces a transparent plastic! That could also be an interesting one to try for your experiments/videos...? Information on alkali/urea cellulose plastics is severely lacking.
Thanks again!
Sounds very enticing as a vid idea!
Will the jelly compound dissolve in the filtrate if it's not filtered out instantly?
4:19 not really understanding the reaction here.. how is Na2(SiO2)7 possible?
Quantum entanglement
basically NaOH+SiO2--> sodium metasillicite and bunch of different sillicates like Na2(SiO2)7
which then react with sulfuric acid to get create many forms of sillicic acid then some silicic acid decomposes in the presence of sulfuric acid after drying all of the sillicic acid decomposes into K2SO4 and sillicone dioxide(sand) and K2SO4 is water soluable
Where do you get sulfuric acid?
Instead of HCL, can sand be washed with using distilled water and vapors?
No, water doesnt react with calcium carbonate
Please Tate Mac, for what we could use pure silicon? I know that from sand we can extract the salt .
Semiconductors
What is that peice rotating in side the beaker what u call it please
Fun fact silicon dioxide is what blacksmiths used to use as flux for blacksmithing
They put silica sand in the furnace during the smelt to lower the melting point of the ore and used it during the folding process to refine the iron.
Do you think this is useful to use it for plants? Amorf Silicon dioxid?
What do you call this method ?
Two questions. Why didnt you just crush quartz? How did you get other minerals out, such zs zircon etc.
Zircon is acid soluble so it’s washed out with the acid.
Any residual mineral content should be negligible.
Though, maybe there’s some residual calcium sulphate which isn’t as soluble in HCl as most other minerals involved but it’s likely less than a percent.
How do we get colloidal silica?
Would this make better thermite than normal sand?
Good question, I answer that in another one of my videos by saying it doesn't make that good of a yield of elemental silicon as regular sand, but it does react brighter and faster!
And what if i want purify 1kg of sand, how much of hydrochloric acid should i use?
Congratulations! Great job, the best proportion of NaOH is the 60g SiO2 and 80 g NaOH?? Thank you
Does potassium hydroxide react with silicon and dissolve, and what is the percentage, please? Greetings
Does potassium hydroxide react with silicon and dissolve, and what is the percentage, please? Greetings
What formula can use to determine the percentage of pure silicon dioxide ? Help me
What can we make with SiO2
SiO2 + Mg --> Si + MgO
silicon is a semi conductor, very useful
moreover I have read that silica (silicon dioxide SiO2) is quartz, however I'm not sure
You can save yourself a lot of time by starting with water, then dissolving your NaOH, then adding your sand with heat. You can adjust the water to adjust your concentration. This also makes it much much easier to transfer from the pan.
Glass and stainless is fine to use, Do not use aluminum!
+Ryan Williamson Thanks Ryan, your method makes sense but I was 15 when I made this so I followed my source's instructions exactly.
That's pretty good!
thanks!
Hey buddy, is it could be using for spray at leaf ?
I only need your process up to the sodium silicate stage to manufacture geopolymer concrete !
Me too!

Awww I was expecting at least a Z80. 🤣 🖖 👌
Can i use muriatic acid to replace hcl?
In this case yes. You are literally stripping calcium carbonate and iron oxide from the silica in sand
Who gave Jimmy Neutron hydrochloric acid?
Thank you for this video man!
finally i know what do do to start masking a micro cpu
does it had a significant changes if the sand is color black? but still at the beach though
oooh good question. I wouldn't waste your time on that sand. Only purify sand that is composed of mostly SiO2.
Nice video i enjoyed watching it!
+Abby Rose thanks! This was a pretty old video though so you should check out my newer stuff too!
I would definitely check them out!
When you cook silocon dioxide with naoh can you dilute it and become sodium silicate? I would like to make waterglass for coating
I believe this will slow down the rate of reaction significantly if you try to dissolve the SiO2 in aqueous NaOH, but give it a try and let me know if it works!
Oh sith I was half way in and realised this is the wrong video
Walter White would hire this kid in a heartbeat
hey,
Does any change in purity of silicon dioxide if we add extra sulphuric acid
Good question! You should only add sulphuric acid to the sodium silicate in the correct mole ratio, otherwise you could be wasting reagents.
Hi, can i ask what is hydrochloric acid 7.1m? I can buy hydrochloric acid with 10% concentration ,would it be enough to purifying sand?
Or should i buy 33%~37% hydrochloric acid?
you can use the 10% HCl if you like, but the purification process will take longer. If you are starting a home lab, I highly recommend get the 31% HCl that is commonly available at hardware or pool supply stores.
So for first reaction anything that dissolves in HCl should be in the solution including any unused HCl solution. Only solids that should be left are impurities. Some items in the solution should be Fe, Co, Al, Zn, Ni, Sn, Mg, and Au if oxidized. Need to breakout chem book. Having trouble finding what all elements dissolve in HCl. So 10.35g of elements have been expelled in the solution or as a gas.
+Greg L. The theory is that the mass loss is due to CaCO3 impurities.
erm... isnt the HCl reacting with the SiO2 to make SiCl4? if not, then the SiO2 will react with the NaOH to make Na6Si2O7(sodium silicate)? im new to this so im just asking
You’re right about the the SiO2 reacting with the NaOH to form silicate, but the HCl is not able to break the covalent bonds between the Si and O atoms, and SiCl4 will never form when they are combined.
Good vid! Pretty sure NaOH eats through copper. Keep going!
Wow! What can you do with silicon dioxide?
Eat it
@@rvnaumenko5 NOOOO
can you just get sand then heat it and expect it to melt and shape it in fiorm of glass?
not usually, no. Almost all sand has impurities like the carbonates seen in this video. You should purify your sand by this process before melting the SiO2 into glass. Make sure you are using a furnace that can reach 3,200˚F otherwise you'll just heat up the SiO2.
Great video dude, all I want to say tho is please wear gloves even when working with non toxic or corrosive chemicals, just as good practice :) loved the video tho :P
you have any Journal paper related to this work
Hello, i am gonna to do my project of silicon from sand.may i get any pdf if you have please send it.
Super! Thank you very much!
Cool! Name turn it into a ttl Microchip!
thanks
Does it mean we consume aand if this some.in.foods
SiO2 is litteraly just sand tho
Very nice video 👏👏👏👏
Would it be safe to eat this? I found out it is the main ingredient in my Spanish brand sodium bicarbonate powder that I use for my upset stomach. Sounds sketchy lol
Haha i think the product would be inert enough to eat, technically. BUT DONT DO IT
Can i use HCl in stead of the HSO4 because its very hard to get in Holland... We dont use it as a drain cleaner i guess...
Yes you can!
Thanks mate! I just finished the reaction of the crude SiO2 and NaOH . Now i'm letting the reaction products dissolve overnight. Can't wait to see the results! Thanks for the info and the awesome video!
Would sulfuric acid work for cleaning the sand? I have to make my hcl, so I'd rather use somethin I already have.
Yes! The sulfuric acid will dissolve the impurities fine!
+Tate Mac Thank you.
What is the concentration of sulfiric acid ?
I need the answer a soon as possible
95%
4:57 the song suits the action
Can you tell me how many % of SiO2 in crude SiO2? is it more than 98% or less?
thanks.
+teddy susanto honestly it's probably around 95%
Можно было бы считать завершенным опыт если бы растворил кремний в воде)Но то уже и в следующем видео можно сделать
Can i use 30/° sulfuric acid
I think you can use 30% but it will take a larger volume. Thanks for asking!
@@BackMacSci i have a pink results is that normal
Do you mean pink results as in your silicon dioxide product is pink?
@@BackMacSci yes
Excuse me, why is it the "grt" sound is produced when H2SO4 is added into the Na2SiO3 solution???
it may be the sound of a small amount of water turning into steam very quickly as a result of the sulfuric acid disproportionating.
Thank you so much. Excuse me, do you have any idea on how to make silica gel which act as a stationary phase on tlc plate?
Or silica gel which use to absorb moisture.
Does this experiment suitable for river sand ?
If the river sand is silicon dioxide-based then yes!
Mmmm my Mountainhouse dry freeze food contain Si02. Delish!! 😁
How to calculate the percentage?
Hmmm, percentage of what?
do you have documents about this procedure ? with your name on it so i can cite your work
I don't have documents. But feel free to just cite the video link!
thank you very much
