Hypophosphorus Acid
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.
Formula: H3PO2 But it is a monobasic acid.
It is H3PO2 .

H3PO2 is monoprotic because it has one ionizable hydrogen atom. When it dissociates in solution, it releases one H+ ion.
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.
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.
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
