1. Detail description:

HS code: 281520
CAS No.: 1310-58-3
Chemical Formula:KOH
Appearance: White flakes or colorless liquid

Potassium hydroxide is a common inorganic base with a chemical formula of KOH and a molecular weight of 56.1.White powder or flake solid, melting point 380 ºC, boiling point 1324 ºC, relative density 2.04 g/cm3, refractive index n20/D 1.421, vapor pressure 1mmHg (719 ºC).
Similar to sodium hydroxide, it is highly alkaline and corrosive, and the pH of 0.1 mol/L solution is 13.5.
Very easy to absorb moisture in the air and delirium, absorb carbon dioxide and become potash.
Soluble in about 0.6 parts hot water, 0.9 parts cold water, 3 parts ethanol, 2.5 parts glycerin, slightly soluble in ether.A great deal of heat is produced when dissolved in water, alcohol, or treated with acids.
Moderate toxicity, half lethal dose (rats, via mouth) 1230 mg/kg.
