Give the disproportionation reaction of H3PO3.

On heating, orthophosphorus acid (H3PO3) disproportionates to give orthophosphoric acid (H3PO4) and phosphine (PH3). The oxidation states of P in various species involved in the reaction are mentioned below

\(4H_3 \overset{+3}PO_3\) → \(3H_3 \overset{+5}PO_4\) + \( \overset{-3}P H_3\)
