Properties:
Phosphorous acid is a colorless crystal. It can be slowly oxidized to phosphoric acid in the air. When heated to 180 ° 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 hygroscopicity.
Relative Density: 1.651 (21.1 ° C)
Melting Point: 73.6 ° C
Boiling Point: 200 ° C (Decomposes)
Solubility: Easily soluble in water and alcohol.
Applications:
Phosphorous acid is mainly used in the production of phosphates, synthetic fibers and organophosphorus pesticides, etc...It is also used in producing high performance water treating agent ATMP.
