Characteristic
Potassium Acetate Hydrate is a moderately water soluble crystalline Potassium source that decomposes to Potassium oxide on heating.
Chemical formula:KCH3CO2•xH2O
Molecular Weight:116.157g/mol
Appearance:White powder or crystals
Density:1.8 g/cm3 (20 °C);1.57 g/cm3 (25 °C)
Melting point:292 °C (558 °F; 565 K)
Boiling point:Decomposes
Solubility in water:216.7 g/100 mL (0.1 °C);233.8 g/100 mL (10 °C);268.6 g/100 mL (25 °C);320.8 g/100 mL (40 °C);390.7 g/100 mL (96 °C)
Solubility:Soluble in alcohol, liquid ammonia;Insoluble in ether, acetone

Application
Potassium acetate is used as deicer to remove snow and ice from the surface and is considered as a replacement for calcium chloride or magnesium chloride. It is used as a food additive; as a buffer in biological research; as extinguishing agent used in class K fire extinguishers and as a catalyst to produce polyurethane polymers. It is utilized for the precipitation of dodecyl sulfate bound proteins thereby removal of proteins from DNA. It plays an important role for preserving tissues, fixation and mummification. .
