Complaint
Potassium hydroxide (chemical formula: KOH, formula weight: 56.1) white powder or flaky solid. The melting point is 380°C, the boiling point is 1324°C, the relative density is 2.04g/cm3, the refractive index is n20/D1.421, and the vapor pressure is 1mmHg (719°C). Strong alkaline and corrosive. It is easy to absorb moisture in the air and deliquescence, and absorb carbon dioxide to form potassium carbonate. Soluble in about 0.6 parts hot water, 0.9 parts cold water, 3 parts ethanol, 2.5 parts glycerin. A lot of heat is generated when dissolved in water, alcohol or treated with acid. The pH of the 0.1 mol/L solution is 13.5. Moderately toxic, the median lethal dose (rat, oral) is 1230 mg/kg. Soluble in ethanol, slightly soluble in ether. It is extremely alkaline and corrosive, and its properties are similar to those of caustic soda.
