Properties

Sodium Phosphate, Tribasic, occurs as white crystals or granules or as a crystalline material. It may be anhydrous or contain1 to 12 molecules of water of hydration. The formula for acrystalline material is approximately 4(Na3PO4·12H2O)-NaOH. It is freely soluble in water, but is insoluble in alcohol.The pH of a 1:100 aqueous solution is between 11.5 and 12.5.

Application

Used as a water softening agent, cleaning agent in electroplating, color fixer in fabric dyeing and flux in enamel ware manufacturing and so on.
