Product Description
Potassium Hydroxide (also named as caustic potash)is an inorganic base with a chemical formula of KOH and a molecular weight of 56.1. It is a white powder or flakes solid at a common temperature. The character is similar to sodium hydroxide, which is strongly alkaline and corrosive. The pH of a 0.1mol/L solution is 13.5. Easily absorb moisture in the air and deliquescence, absorbing carbon dioxide to form potassium carbonate. It is soluble in water, ethanol, glycerin, and slightly soluble in ether.
