Applications
Phosphorous acid is mainly used in the manufacture for phosphates,
synthetic fibers and organophosphorus pesticides, etc...It is also
used in producing high performance water treating agent ATMP. It\'s
used as reducing agent in chemical reaction.
Properties
Phosphorous acid is a colorless crystal. It can be slowly oxidized
to phosphoric acid in the air. When heated to **0 ° C, it can be
decomposed into phosphoric acid and phosphine (highly toxic). As a
dibasic acid, it has slightly ber acidity than phosphoric acid.
Phosphorous acid has b reducibility and can easily reduce AG+ to
metal silver. It can also reduce sulfuric acid to sulfur dioxide.
It is corrosive and has b hygroscopicity.
Relative Density: 1.**1 (*1.1 ° C)
Melting Point: *3.6 ° C
Boiling Point: **0 ° C (Decomposes)
Solubility: Easily soluble in water and alcohol.
