Description
White powder or crystal. The relative density is 2.534, and the melting point is 980 ℃. Colorless transparent crystal or white crystalline powder. Easily soluble in water, the solubility of 100g water at 20 ℃ is 6.23g, and its aqueous solution is alkaline; Insoluble in alcohol. The aqueous solution is stable below 70 ℃, and hydrolyzes to disodium hydrogen phosphate when boiling. It is easy to absorb moisture and deliquescence in the air. It can form complex with alkaline earth metal ions; When it meets Ag+, it generates white silver pyrophosphate.
Applications
