I am doing a project for when sodium acetate is supercooled and then when disturbed goes from a liquid at room temperature to a crystallized solid in an exothermic reaction that leaves it quite warm.  This is how handwarmers work. I was just hoping someone could give me some ideas on how this process works so I can better explain it in my project.

To help you understand how a solution can be supersaturated, and not crystallized, you should try to look up how crystallization affects the entropy of a system.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Dear DHohrath;

Beside of possible Entropy Phenomena  -  We have such already discussed under:   

Good Luck!
