Sodium Phosphate Dibasic 99% AR Grade Reagent
Cas Number:10039-32-4
Formula: Na2HPO4·12H2O
Molar Mass:358.14
EC Number:231-448-7
Physicochemical properties:
Colorless translucent crystal or white granule powder. It is easy to lose 5mol of water and weather in the air. It will lose all crystal water at 100 ° C. It can be dissolved in 3 parts of water, almost insoluble in ethanol. The aqueous solution is alkaline and the pH is 9.5. Its heptahydrate is relatively stable in air. The relative density is about 1.5. The melting point is 34 ~ 35 ° C.
Usage:
Used as a buffer in the analysis.Determination of serum potassium. Fire retardant.
Packing:
500g/25kg
