7.49 Give the disproportionation reaction of H₃PO₃.

7.49 

Disproportionation is a chemical reaction typically a redox reaction where a molecule is transformed into two or more dissimilar products.

On heating, orthophosphorus acid (H₃PO₃) disproportionate to give orthophosphoric acid (H₃PO₄)

and phosphine (PH₃). The oxidation states of Phosphorous in various species involved in the reaction are mentioned below.
