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 b 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.
