Don't Put Water on Chalk-Quicklime
HTML-код
- Опубликовано: 20 июн 2024
- In this video I show you how to make quicklime CaO and what happens when you put water on it. This reaction turns CaCO3 (chalk) into quicklime by releasing CO2.

I work at a chemical plant. We used to put quick lime in this one product which came in huge bags. And if you threw the bags away in the open top dumpster, when it would rain it would catch the bags on fire from the chemical reaction.
normal people when they see rain: ah there goes the rain
the people at the chemical plant: oh god call the fire brigade

xDDD
And that's what I call good fun.
i think he accidentally edited out the footage that showed the lime light lol
@Michael John O’Neill. I think you are right bc I thought I’d missed something at first.
I got the same thought
He did.
OOF lol
yup
I didnt see any limelight, just little red glow.

Because it needs 2300 degree Celsius. For that effect.
Fun fact: Calcium Oxide is used a lot in Japanese bento boxes (lunch boxes you have when you take a bullet train from one location to another.)
You pull a string, which causes a water packet and the calcium oxide to react and heat the food.
I suppose this is a similar reaction as used in the "Hand Warmers" packets? In those packets, I believe that an iron chemical is used, but all the same, it is an exothermic reaction! 😀
People eat chalk all the time, the active ingredient in Tums is calcium carbonate
Hes probably worried about impurites or other chemicals from products marketed as edible chalk. Or just regular chalk. Since its prob not regulated like Tums would be.
Ight imma eat chalk now I never thought of that!
Thank you for mentioning this. You can actually overdose from from calcium carbonate
Some extra knowledge -
In India (I am a native Indian) people often chew paan ( Paan is a preparation combining betel leaf with betel nut) on various occasions. They use lime for a basic taste. So they bring lime from market which is clean and mix in with water and keep it in a glass jar aside for like 12-16 hours until it gets creamy. They jar gets so hot between this interval and bubbles form. Even I do this sometimes on some family occasions. Believe me the jar gets so so so hot. Lmao I get so scared sometimes that the jar will actually break but it doesn't :)
I've had meetha paan before, I liked it a lot, pretty sweet, though it's a little unhealthy 😅
Relatable
Shouldn't this be "don't heat chalk and then put water on it?"
After seeking out actual chalk that is apparently hard to find.
Forget water, we shouldn’t heat it in the first place!
Schoolboy trick from more than five decades ago: wet the chalk, write something improper on the board, when it dries, it's nearly impossible to remove.
In kindergarten I put small pieces of chalk into the eraser and it took my teacher a while to realize it as she kept erasing while simultaneously making lines. She did not take it well. She was a B.
Thanks for warning me, I was just going to put water on chalk!
Marijo Pilić wow! Me too!

i put water on chalk that i took from school and i crushed the chalk and added water but nothing happened probably because it isnt the thing in the video

I thought it is common sense.
Calcium Carbonate is a perfectly edible ingredient in heartburn remedies used to neutralise stomach acid. Quicklime is also used as a pickling agent. I used to slake lime to create hotlime mortars by the ton. I work with it every single day and consider it to be a wonder material, but must be used with caution. I've suffered 2nd degree burns from this stuff, but not through the process of slaking, but from exposure to the hydrate combined with friction in a wet environment. It's extremely caustic. Also, you cannot reuse it in the way it is suggested here, once CaO has reacted with water the Hydrated Lime Ca(OH)² must first react with CO² dissolved in water (or in combination with water and
CO² present in the air) and cure into CaCO³ (Calcium Carbonate) before it can be burned and slaked once again. This reaction is extremely slow. It's known as the lime cycle. It isn't as simple as just re-heating the hydrate.SHFPs that use quicklime are single use only.
Yep. Active ingredient in Tums.
@@ShadowoftheDudeInteresting! I just looked on Google images at the ingredients list, and depending on the product, it may be 500mg, 750mg, or 1000mg calcium carbonate per Tums. I don't yet see the total mass of a Tums, so I don't know what percentage by mass it is.
It would be a funny prank to get some Tums preheated, like put them in the oven under the broiler for a while so that they become quick lime, put them back in the bottle, then show a friend "look what happens when you put water on a Tums!" Then they would go to the store and buy some and try to recreate it only nothing happens 😜
Sir are chemical engineer or chemist??? Please reply. I want to ask a question
Remembering old school days with this experiment!!
"It's called the limelight."
*Rush has entered the chat*
yeah
Funny, I _just_ learned about the origin of the term "limelight" a couple weeks ago when watching an episode of "Penny Dreadful". They mentioned "limelights" as actual things instead of an expression, so I paused to look it up.
Quicklime has had some interesting uses throughout history. Some of the more notable examples are the production of cement and the processing of corn and other grains in the Americas. That second one is my favorite. It's called "nixtamalization", from the Aztec word "nixtamalli". If you grind dried corn, it won't absorb much water. But if it's pre-treated with quicklime, you'll have something completely different. More nutritious. More aromatic. And more workable as a dough. Without nixtamalization, you can't have corn tortillas or tamales. Imagine that.
I've seen "lime" as an ingredient on a particular brand of tortilla chips, I can't remember which, and it wasn't the citrus "lime". I remember the texture being a little bit more different than normal tortilla chips, like more pasty but in a good way.
@@adamcolbertmusic I wonder if that means they're starting from corn and nixtamalizing it themselves, instead of purchasing prepared masa from a supllier. I think that would require them to include lime in the ingredients list. Whereas a chip maker that purchases masa _might_ _maybe_ get away with just putting "corn" on the list, since after nixtamalization all of the calcium hydroxide used in the processing of the corn is washed away, leaving just the very-changed corn behind.
@@tom_something I will look at the ingredients on the tortilla chips the next time I'm at the store!
90% of the people don't know what is the telling but 100% of us are interested in his expriment.
This is fascinating. I've always been intrigued by pre-electric light generation, but your limelight demonstration at 2:30 didn't seem to produce the desired effect. I'd be interested in seeing a more detailed experiment involving this.
Quick random fact, quicklime was also used in roman concrete.
I've heard you can also use egg shells or snail shells to make quicklime instead of chalk.
It is a component in portland cement as well...
@@Just_Sara That's because those shells are made of calcium carbonate (CaCO3), the thing that is in chalk.
CaCO3 + heat -> CaO + CO2
(quicklime)
@@gamistry2947 I know, right, isn't that rad?! :D

So, what do you think😁😁
I would like to see it
Just ask backyard scientist to do that.
Yes! I came to the comments section just to say this. Maybe Hydraulic Press Channel will do it.
EARTH WILL DIE
Probably nothing would happen if it was just normal chalk
i cant stop staring at the mustache it looks amazing u look like an undercover cop

Chalk doesn't have an exothermic reaction with water, he's being very disingenuous with that line. He turns the chalk into quick lime before he adds water.
This guy sound like he is asking a question every sentence he says.

My grandmother used to paint walls with a mix of quicklime and water.
I remember her preparing it in a metal container ...The water would boil and lots of vapour would come out.
Tens of liters of water boiling with some 4 or 5 big chunks of quicklime.
Slaked lime
wow i learned how self cooking meals work and where the word limelight came from. thanks!! great video 😃👍🏽
It's funny that you mention "eating chalk". While a lot of the cases of people eating "normally not edible" inorganic substances (like chalk, drywall, and dirt), there are documented cases of people unknowingly doing this to make up for some nutritional deficiencies.

I do recommend eating a bit of chalk to ease the symptoms of acid reflux and other problems related to acidity in the stomach. It's marketed in grocery store as TUMS.

In the UK we've been putting water on quicklime for hundreds of years, it's used to make lime morter, the bricks in the house I live in are held together with lime morter.

This is a very good video that satisfies a STEM beginner’s curiosity about limelight.
Thanks man it improves my chemistry
I work at a steel mill that uses literal tons of this stuff, when we clean the transfer houses we use water and this reaction happens in mass, perhaps I should record it next time.
I'm buying this kind of chalk and drawing pictures all over my driveway! Can't wait until it rains! Another cool video!

Hey, make an experiment on "Tungsten ". I think it would be great!
I remember when they painted the house, they used lime.
When they mixed water it used to get very hot and started boiling and steaming ...
I could feel the heat from 2-3 metres away!
Actually, a few old theater houses that used limelights exploded in fireballs when the bladders they used to hold hydrogen and oxygen for the lime either leaked or caught fire.
Very cool!

amazing videos!
you're epic and i love your channel :)
As a non native English speaker, I've always been curious about the origin of words or expressions. Today I actually learned something new about limelight. Thanks!
Ur new mustache looks epic
I crave chalk like crazy. I have all my life. As well as candies that are primarily calcium carbonate. So happy to find out I can order this chalk to eat.
Totally cool.
Love your channel and I watch every video even tho I'm not into physics at all, but I have to say GET RID OF THAT STACHE MANNN
Bro I have that exact Belgorod chalk. Something about chalk is so satisfying to munch on.
Excellent! *Request* ... Take II of the _forbidden color_ ?
Why you should out water on chalk,
Me: oh I thought you need clocks.
I’m sorry 😞
You can 100% do the same thing with shells either snail shells or seashells (I believe 🤔) it was used to make concrete.
Nice stache 👌
Keep making great videos like this 👌👌👌👌👌👌👌👌
In indonesia traditionally people consume areca nut or leave, betel leave, and active (will release heat when mixed with water) or inactive lime. We only chew them together, will get the effect of getting high and a little addictive. When the mix is not releasing any effect anymore we spit them.out. the spit is as red as red paint
Hmm what if someone ate..
Real Chalk..
😁😁
Good thing it's not Ca(m)! Very cool!
Fun short video. SHORT videos are great
Hey!-I recall seeing something like this a few years ago in a History Channel show about the construction of White House. The stones that were used to build the WH weren’t white; quicklime was used to “whitewash” the stones, and the demonstrated how it was done.
For *sometime* after that, I was *musing* about the possibility of perhaps “MacGuyver”-ing this into-...I dunno-something “thermoionic”? A fuel cell thingee, perhaps?
Anyway-I’d forgotten about all this until coming across this video now...
There are some self-heating packed foods using CaO as the heat source. You just add tap water and leave it for a few minutes and it’s piping hot. So chalk is not hard to buy after all XD
Action lab is the best science channel
"Real Chalk is hard to find..."

Calcium carbonate is used in many thing - food supplement for pets (it is already mixed into commercial pet-food but for homemade food might be required to be added extra), as part of a backing-agent, acid-balancer and more.
For other applications you do not require food-grade CC which is then of course quite a bit cheaper.
You can bake it and then use as mortar (many european barns are whitewashed with that). And darn is it fun (cause of the danger) when mixing several kilogram of that with water :)

I used to like learning from these vids but I can only look at the moustache. :P
we have things called kapur sirih, which literally chalk & betel leaf. is actually well known around SE Asia you can find the wikipedia page titled Paan.
its no longer recomended though concerning the health risk, but some eldery still did it.

Action Lab pulling off that Tesla look.
Long time no see buddy. I'm finally interested in science again.
Limelight, ah interesting :D
Antacid tablets are calcium carbonate too. Basically flavored edible chalk.
Also, couldn't this reaction be used to heat homes during the winter? I'm not sure how long it takes for all the water to evaporate but it seems like a pretty renewable source of heat.
Thanks for the great explanation, but the limelight didn't come out as well. Is it white light or is it colored?
