Potassium hydroxide (chemical formula: KOH, formula: 56.1) white powder or flaky solid. The melting point is 380 DEG C, the boiling point is 1324 DEG C, the relative density is 2.04g/cm3, the refractive index is n20/D1.421, and the vapor pressure is 1mmHg (719 DEG C). Strong alkaline and corrosive. Easy to absorb moisture in the air and moisture, absorb carbon dioxide and potassium carbonate. Dissolve in about 0.6 portions of hot water, 0.9 cold water, 3 portions of ethanol, and 2.5 portions of glycerin. Produce large amounts of heat when dissolved in water, alcohol, or acid. The pH of 0.1mol/L solution is 13.5. Moderate toxicity, median lethal dose (rats, through mouth) 1230mg/kg. Soluble in ethanol, slightly soluble in ether. Highly alkaline and corrosive, similar in nature to that of caustic soda. Moderate toxicity, median lethal dose (rats, through mouth) 1230mg/kg.
