Potassium Iodide

Potassium iodide is a crystalline salt, with a neutral pH because its iodide and potassium ions do not react with water. Potassium iodide is used in photography to prepare emulsions. It is a product widely used in science experiments as it acts as a catalyst in chemical reactions, accelerating the reaction.
