      Hexametaphosphate

      Hexametaphosphate: Molar mass: 611.77 g · mol-1  Appearance: white, odorless, crystalline powder, Hexametaphosphate Density: 2.484 g / cm3  Melting point: 616 ° C (decomposition)  Boiling point: 1500 ° C.

       

      Hexametaphosphate is a kind of Sodium metaphosphate polymer, which is a transparent glass flake or white powdery crystal. With the features of high moisture absorption; it becomes sticky after moisture, easy to dissolve in water with good dissolution but the rate is slower; and aqueous solution is acidic. For some metal ions (calcium, magnesium), Hexametaphosphate has the ability to produce or soluble complexes, it can be used to soften water, and lead, silver, barium salt and can also generate complexes.
