Give the disproportionation reaction of ...

Give the disproportionation reaction of `H_(3)PO_(3)`.

Text Solution

Verified by Experts

`H_3PO_3` on heating undergoes disproportionation i.e., self-oxidation-reduction to form `PH_3(O.S.ofP=-3)` and `H_3PO_4(O.S. of P=+5)`.
`H_3PO_3overset(Delta)toPH_3+H_2PO_4`
