The short statement of this is that H3PO3 is a tribasic acid (3 x OH) and H3PO2 is a mono basic acid (1 x OH) 1. * These acids have only one hydrogen atom to donate to a base in an acid base reaction just because they have one replaceable hydrogen they are known as monobasic. Check Answer and Solution for above question Answer (1 of 2): Basically it because of the structure.H3PO4 is O-H / O=P-O-H \ O-Hso each H+ can be removed to leave -Ominus.H3PO3 is O-H /O=P-H \ O-HPminus is just too unstable compared with Ominus. In H 3 PO 3 there are two O-H bonds, connected to phosphorus. (a) H3PO2 (b) H3PO4 (c) H3PO3 (d) H4P2O7 Phosphorous acid is the compound described by the formula H 3 PO 3.This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Oxygen is more electronegative, but I reacon its more complex than that. Phosphorous Acid (H3PO3) - Phosphorous acid is a diprotic oxyacids of phosphorus with the chemical formula H3PO3.
