Chemical formula : （KPO3)n
Molecular weight: 118.07
CAS Number: 7790-53-6
EINECS No.: 232-212-6
Properties
Highly polymerized linear-chain polyphosphates, there may be a small amount of cyclic structure of potassium trimethenate and ring structure of potassium tetrametaphosphate. It is a colorless to white glass-like block or sheet, or a white fibrous crystal or powder. Odorless. Slowly dissolved in water, its solubility varies with the degree of polymerization, generally 0.004%. The aqueous solution is alkaline. Soluble in sodium salt solution, rapidly soluble in dilute inorganic acids, insoluble in ethanol.
