Potassium hydroxide is also known as "caustic potassium", the chemical formula KOH. It is often white and flaky. It is easy to dissolve in water, ethanol, strong heat release when dissolved, and easy to absorb water and carbon dioxide in the air. Used for analysis reagent, used for making soap, paper making, textile, printing and dyeing, pharmaceutical, electroplating and other chemical industry and organic synthesis.

Chemical property
Potassium hydroxide is a strong base that can be completely dissolved in water to produce a potassium hydroxide solution, which is alkaline and can neutralize acidic substances. Non-combustible, highly corrosive. In contact with water and steam, a large amount of heat is released, forming a corrosive solution. Neutralizing reaction with acid and exothermic.
