H3PO2 is the chemical formula for phosphorous acid. It is a diprotic acid commonly used in the production of pharmaceuticals, flame-retardants, and metal surface treatment.
H3PO2 is known as phosphorous acid.
The oxidation number for H in H3PO2 is +1, as it is in compounds with nonmetals. The oxidation number for P in H3PO2 is +1, as the sum of oxidation numbers in a compound is zero.
H3PO2 is monoprotic because it has one ionizable hydrogen atom. When it dissociates in solution, it releases one H+ ion.
Hypophosphorous acid (H3PO2) has a lower oxidation state of phosphorus (+1) compared to phosphoric acid (H3PO4) which has a higher oxidation state of phosphorus (+5). Compounds with lower oxidation states are more easily oxidized and therefore act as reducing agents, while those with higher oxidation states do not readily give up electrons and therefore do not act as reducing agents.
Sodium hypophosphite (Na2HPO3) is a basic salt because it is the product of a strong base (sodium hydroxide, NaOH) reacting with a weak acid (hypophosphorous acid, H3PO2). This means the salt will hydrolyze in water to form a basic solution.

The chemical formula of calcium hypophosphite is Ca(H2PO2)2.
The oxoacids of phosphorus include ones with formulas H3PO4, H3PO3, H3PO2, HPO3, and H4P2O7.
H3PO2 a phosphorus oxoacidand a powerful reducing agent, HOP(O)H2 exists in equilibrium with the minor tautomer HP(OH)2
Hypophosphorous acid is a phosphorus oxyacid with the chemical formula H3PO2. It is a weak reducing agent and is commonly used in industrial applications for metal plating and as a reducing agent in organic synthesis. It is a colorless, odorless liquid at room temperature.
