In the following reaction, 4P+3KOH+3H(...

In the following reaction,
`4P+3KOH+3H_(2)O rarr 3KH_(2)PO_(2)+PH_(3)`

A

only phosphorus is oxidized

B

only phosphorus is reduced

C

phosphorus is both oxidized and reduced

D

phosphorus is neither oxidized nor reduced

Text Solution

Verified by Experts

The correct Answer is:
C
In the given reaction, O.N. of P=0, in `H_(2)PO_(2)` it is +1 and in `PH_(3)` it is -3 . Hence P is both oxidized and reduced.
