Hypophosphorous acid |
| 1, Molecular Formula:H3PO2 |
| 2,Molecular weight:66.0 |
| 3,Properties:The pure form of this
product is a colorless crystal with the density
of (19°C)1.493 and the melting point of 26.5°C.
It can be mixed with water in any proportions.
Being a strong reducer, it can be easily oxidized
in air. If the anhydrous acid is heated to 130-140°C,
it will be decomposed into PH3 and H3PO4 . |
