Potassium hydroxide, is an inorganic compound, chemical formula for KOH, is a common inorganic alkali, has a strong alkaline, 0.1 mol / L solution of pH 13.5, soluble in water, ethanol, slightly soluble in ether, very easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide and become potassium carbonate, is mainly used as a raw material for the production of potassium salts, but also used in electroplating, dyeing and so on.

Basic information

Nature: White or slightly yellow bean shaped particles, rods, or blocks. Melting point approximately 360 ºC, d 2 044. 380 ºC is anhydrous. It is highly hygroscopic and deliquescent in the air, absorbing carbon dioxide to form potassium carbonate. Dissolve in 0.9 parts of water, 0.6 parts of boiling water, 3 parts of ethanol, and 2.5 parts of glycerol, while releasing a large amount of heat. Insoluble in ether. The pH value of the Imol/L aqueous solution is 13.5. Non combustible and highly corrosive. When exposed to water and steam, a large amount of heat is released, forming a corrosive solution. Neutralize with acid and release heat.
Appearance:This product is a white solid, in the form of small pellets, thin sheets, rods, or other shapes; Firm and brittle, with crystalline fracture surfaces; Easy to absorb moisture and carbon dioxide from the air.This product is highly soluble in water and easily soluble in ethanol.
