physical_description
Polymeric sodium metaphosphates: Clear hygroscopic solid; Soluble in water; [HSDB] White odorless granules; [MSDSonline]
solubility
CLEAR, HYGROSCOPIC GLASS; MP 628 u00b0C; SOL IN WATER, BUT DISSOLVES SLOWLY; DEPOLYMERIZES IN AQ SOLN TO FORM SODIUM TRIMETAPHOSPHATE & SODIUM ORTHOPHOSPHATES. /POLYMERIC SODIUM METAPHOSPHATES/
decomposition
When heated to decomposition it emits toxic fumes of phosphoxides and Na2O.
other_experimental_properties
It possesses sequestering, dispersing, and flocculating properties and precipitates proteins. In very low concentrations, it inhibits corrosion in steel and prevents the precipitation of slightly soluble, scale-forming compounds such as calcium carbonate and calcium sulfate. /Calgon/
