Thanks for the great video. I have cooked limestone in the past and was amazed after I let I cool and then dipped a piece of the stone into water. The solid superheated and began to disintegrate in front of my eyes. My children thought it was great, I thought it was awesome! I have been trying to make a decent concrete from the slacked lime. Sadly it disintegrates fairly easily after drying. I still have some learning to do.
You need the organic matter to make it strong again is not strong because you removed the organic with fire. If you find out how to put it back let please let me know. I'm looking into how the Aztecs used CaCo3
Nicely explained video.I use lime putty in my work and much prefer it to cement and hydraulic lime.One question,why does hydrated lime not set? Also, somebody once explained that the difference between lime and cement is not only does lime use less energy to produce it but cement has clay in it which makes it non-porous and yet if you want your lime putty mortar to set faster you can either add a pozzilan or else add powdered clay,but surely that's turning it into a cement which defeats the object of using the lime putty doesn't it?
it sets slowly as it reacts with atmospheric CO2. Yes clay is one source of material to make cement but not the only one. A few different processes go on in cement, some responsible for early set, some for slow strength development, all related to chemical hydration. Just what I remember from my civil engineering days
There are degrees of hydraulicity and as a result flexibility and breathability too. Cement is at the top, putty at the bottom with NHL's in between. Eg. adding metakaolin to hotmixes makes them as strong as NHL3,5. Lime putty is only really for fine plaster you should use hot mixes. Hydrated does set, just very slowly and you could add a pozzolan like brick and just use it like NHL if you really wanted to. Hydrated is from the same lime as putty but with 10-15% water added as oppossed to 100% for putty and non for quicklime.
Limestone or calcium carbonate can be soluble in acidic pH. if more CO2 will be introduced to the solution (giving temperature is low enough) it will be dissolved again to Ca and CO3
Very nice video and indeed helpful. There is a query, is it possible to collect carbondioxide in a gaseous state from calcium carbonate thermal decomposition?
Since the gases coming off from limekilns are almost pure carbon dioxide it would be sensible to try to capture it - perhaps by pumping it into old gas or oil wells. Currently in UK some research has been undertaken but it is in its early days. www.gov.uk/guidance/uk-carbon-capture-and-storage-government-funding-and-support
@@fuseschool Thank you very much. Just one question, is it possible to collect carbondioxide in a gas storage bag or some glass vessel? Just a Laboratory scale experiment.
What!? 0:55, Millions of years ago? This process can occur in a much much smaller time frame, like thousands of years. Lets not blame everything on large numbers for convenience.

Clearly explained video.The narrator has a very clear voice.Well done.
Mam plz tell me about limestone ingredients
*She is explaining everything so clearly 😊*

I never realized how good youtube videos helped. very clear voice and the summary helped a lot thanks!
Awesome! Glad to hear it! And glad it helped 🙂
it is pretty clear, good visual
Thank u so much for explaining this clearly
You're so welcome! 🤗
Wow! This video exceeded expectations. ...way to raise the bar, thanks!
Anyone else watching this an hour before their chemistry exam 😂
Amazing presentation... Everything is now crystal clear!! Thanks so much....
You're very welcome! 💜
Superb explaination
Thank you 🙂
Thank you so much. I wish if my school like this :(
You're most welcome!
👏👏👏 very nice explained 💖
Nice presentation!
Well Explained...
Thanx..
Thank you!
clearly explained thank u so much...Its
really helps me 😄🥳
Most welcome 😊 Glad it helped!
Super explanation mam. Thank you so much 🙏
You are welcome 😊 Glad you liked it!
This video really helped me! Thank you! 💜
Excellent!
Really help me
Glad it helped!
Summary was really helpful
Superb clear explanation. No nonsence
Thanks a lot!
Limestone or calcium carbonate can be soluble in acidic pH. if more CO2 will be introduced to the solution (giving temperature is low enough) it will be dissolved again to Ca and CO3
when adding co2 to lime water to make caco3 would it be a solid? if not would it be solid once exposed to air?
Clear as crystals, thanks a lot
You're very welcome!
superb video easy to understand
Glad to hear that!
How is Sodium Hydroxide different from Calcium Hydroxide please? is it a lot different?
..what can you say about calcium carbonate suplements?
Amazing explanation
Glad you think so!

Kindly name the apparatus in which caco3 is getting decomposed . I'm finding difficult to comprehend the accent you applied in speaking it's name .
1:33 Limestone can be thermally decomposed in a rotary kiln.
Nice presentation!!!
Thank you!
thankyou mam
You're welcome!
Excellent video
Thank you very much!
Its amazing and mostly helpfull
Glad it helped!
Thank you
Welcome!
thank u
Nice work
Thanks!
The hydrogen carbonate formula is Ca(HCO3)2 not CaHCO3
No bro its CaHCO3 only, who told you it is Ca(HCO3)2
i like her voice😊
Superb
Thanks 🤗
super madam
How come this useful thing got less view?
Andy S Because this is a copy of the original just with a starting bit...
Because no one want to use their had anymore.
* Ca(HCO3)2
Source : NCERT Book for Class X
what is the exact heat ?
800c as far i know
Nice
Thanks
Vid : it will turn clear again
Solution: turns blue😍

How do you know it was millions of years ago?

Deposition to uplifting or subduction can easily take millions of uears
great work.....now ....ersatz milk......yeahr.
tax for saving my chemistry!!!!!!!!
Happy to help!
ok ja a sisti
How I wish these lectures could pronounce English properly. It took me several views to understand certain specific words and the meaning thereof.
Her English pronunciation is absolutely perfect.
