A seed crystal can be dropped into a saturated solution of sodium acetate. The solution will suddenly crystallize and turn to solid. Alternately, the solution may be slowly poured out onto a seed ...

Due to differences in energy density, the crystallization of sodium acetate releases more heat per mole than the hydrogen gas explosion. However, the hydrogen balloon reaction is more dangerous, ...

When it is exposed to air, the iron begins to rust. This rusting process produces heat. The second contains a solution of the chemical sodium acetate and a small metal disc. When the disc is bent, ...

Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and ...

The liquid in the hand warmer is a very concentrated solution of a salt called sodium acetate. The sodium and acetate ions are ready to bond with each other and with water molecules to form a crystal.
