HOT ICE

Hello! Today I have for you a wonderful experiment "hot ice". This experiment can be repeated by anyone!
We need the vinegar (70%) and baking soda.

Mix 1 kilogram of vinegar, 978 grams of baking soda and 200 grams of water. We can observe how carbon dioxide is released!

A few hours later, we got the sodium acetate trihydrate.

We need melt the sodium acetate trihydrate in a pan.

We have obtained a clear liquid.

Put the solution in a bucket of cold water and cover with a lid.

Even a small crystal of sodium acetate is able to start the crystallization process in the cooled solution.
