Sapp (sodium acid pyrophosphate)
Properties:
White powder or granular; relative density 1.86g/cm3;soluble in water and insoluble in ethanol; if its aqueous solution is heated together with diluted inorganic acid, it will be hydrolyzed into phosphoric acid; it is hydroscopic, and when absorbing humidity it will become into a product with hexa-hydrates; if it is heated at a temperature above 220íµ, it will be decomposed into sodium meta phosphate.
