H3PO2 is known as phosphorous acid.
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.
It is actually called HYPOPHOSPHOROUS acid (H3PO2). Its official name (by IUPAC) is phosphinic acid. It is a weak, monoprototic acid, chemically also be 'written' as HOP(O)H2 , so not triprotic like its big brother phosphorous acid H3PO3 .We can prepare it by oxidizing Phosphine (PH3), in Iodine (I2) with water according to the following equation:PH3 + 2 I2 + 2 H2O ----> H3PO2 + 4 HI
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.
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.
Hypophosphorus Acid
Formula: H3PO2 But it is a monobasic acid.
It is H3PO2 .

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.
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 a phosphorus oxoacidand a powerful reducing agent, HOP(O)H2 exists in equilibrium with the minor tautomer HP(OH)2
