Question

Give the disproportion reaction of $H_{3}P{O}_3$.

Answer 1

1)Disproportionation is a type of redox reaction where an element from a reaction undergoes both oxidation and reduction to form two different types of products. Similarly in case of $H_{3}P{O}_3$ gives two products on disproportionation on heating.

2)On heating $H_{3}P{O}_3$ it undergoes disproportionation reaction to give orthophosphoric acid and phosphine.

$4H_{3}P{O}_3⟶3H_{3}P{O}_4+P{H}_3$
