What happens when H(3) PO(3) is heated ?...

What happens when `H_(3) PO_(3)` is heated ?

Text Solution

Verified by Experts

The oxidation state of P in `H_(3)PO_(3)" is "+3`. Since this value is intermediate between the highest (+5) and lowest(-3) oxidation states of P, therefore, when `H_(3)PO_(3)` is heated it undergoes disproportionation to form `PH_(3)andH_(3)PO_(4)` with oxidation states of -3 and +5 respectively.
