    Hypophosphorous acid

    M.F.: H3PO2

    M.W.: 66.0

    Property: 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 mixed with water in any proportion, and it is easily oxidized in air. If the anhydrous acid is heated to 130-140°C, it will be decomposed into PH3 and H3PO4.
