Sodium acetate was introduced to help break down the solar cell’s individual materials. Sodium iodide, by contrast, was added to help reform the separated perovskite crystals so that they could ...

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.

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, ...
