How to Make “Hot Ice” Sodium Acetate with vinegar and baking soda
With just two simple ingredients you can make sodium acetate!
FOREWARNING: This reaction pretty hard to get exactly right, don’t be discouraged if it fails the first time. Thoroughly read the comments and this description to avoid problems. Finally, if it still doesn’t work, message me and i’ll try to help.
Just get 1 liter of clear vinegar and add in 4 to 5 table spoons of baking soda. Then boil the mixture down to 100mL to 150mL.
A more accurate way of finding how much you need to boil can be found in our latest video: http://www.youtube.com/watch?v=21IcpkxgBVY
It should still smell like vinegar. If it does not, add an equal amount of vinegar and boil it back down. Smelling again for the vinegar. Keep adding and boiling until it does smell like vinegar.
Put it into a jar while it is still hot and cover it. Let it cool down to room temperature and then you can do all those “hot ice” vids you see!
If it turns yellow or brown, that’s ok. But don’t boil it too far or it will burn.
If you have a weigh scale, its MUCH better to accurately weigh your baking soda depending on the percentage of vinegar. Use the following masses per 1 liter of vinegar:
4% vinegar use 56g of baking soda
5% vinegar use 70g of baking soda
6% vinegar use 84g of baking soda
7% vinegar use 98g of baking soda
8% vinegar use 112g of baking soda
Gram scales are very easy to buy online and on ebay. It is highly recommended you get one if you’re serious about chemistry.
When adding the baking soda. Go SLOWLY or it will fizz over and make a mess.
What’s happening is the vinegar contains acetic acid which reacts with the sodium bicarbonate from the baking soda to create sodium acetate.
You need to boil it down because the vinegar contains too much water for the sodium acetate to work as hot ice.
When you want to do the “hot ice” freezing reaction, just warm the mixture over a stove or dip in a hot water bath until it completely melts. A microwave also works. Then let it cool down. If you find it freezes by itself when you’re cooling then you need to make sure you completely melt every last bit of sodium acetate. You can also cover the container to prevent it from drying while cooling down. The drying will cause it to freeze before you can use it. Covering it stops this.
Once it’s liquid and cooled, have fun!
Thanks for watching!

Sodium Acetate is NOT edible! It’s not toxic but it doesn’t taste very good. So don’t use it as actual ice.
When it quick-freezes it actually warms up. That’s why it’s called “hot ice”. When it’s completely frozen it’ll stop warming up and cool down to ambient temperature.
If you want sodium acetate powder, it’s probably better to buy it directly off ebay. If you want to convert this stuff into a powder then first make sure you got the mixture right and that it actually works as hot ice. Then pour it out on a tray to solidify it and mash it up with a spoon. Leave it to dry overnight and mash it up further if it’s still sticky. Eventually it’ll dry to a powder and you can save it that way.
The yellow thing in the bottom when I’m adding the baking soda and boiling is a magnetic stir bar that stirs the ingredients.
