Applications 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.

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.

Agrochemical :Phosphorous acid is used to prepare phosphite salts, such as potassium phosphite, which serve as excellent agricultural fungicides. These salts, in addition to aqueous solutions of pure phosphorous acid, are very effective in controlling a variety of microbial plant diseases. An important and nutritious element in all living species, phosphorous compounds are also applied extensively as fertilizer e.g. phosphites, phosphonates or phosphates.

Life Science : Used in chemical reactions as a reducing agent that is somewhat less vigorous than the related Hypophosphorous Acid

Oil & Gas : Phosphorus based compounds are used extensively in the oil industry as additives. These chemicals have properties which aid lubrication, oxidation and inflammability. They also have good thermal and cold resistance attributes. e.g. tributyl phosphate, tris(2-ethylhexyl) phosphate

Plastics & Polymers : Phosphorus compounds are used as PVC stabilsers to prevent decomposition and impart enhanced resistance to daylight, weathering and heat ageing. As lead based stablisers are being phased out within Europe, materials such as calcium phosphite are now widely used.

Water Treatment : One of the most important use of phosphorous acid is the production of phosphonates for industrial water treatment. Phosphonates are employed as chemical additives to function in a wide range of antiscalants and corrosion inhibitors, because they have high stability in the presence of oxidizing agents e.g. 2-phosphonobutane-1,2,4-tricarboxylic acid.
