In the reaction P4 + 3 KOH + 3H2 O to ...

In the reaction
`P_4 + 3 KOH + 3H_2 O to PH_3 + 3KH_2 PO_2`

A

Reduced

B

Oxidised

C

Oxidised and reduced

D

Neither oxidized nor reduced

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(4)+3KOH+3H_(2)O to 3KH_(2)PO_(2)+PH_(3)`
O.N. of P in `P_(4)`=0
O.N. of P in `KH_(2)PO_(2) =+1`
[1+2+1+x+2(-2)=0
1+2+x-4=0 or x=1]
O.N of P in `PH_(3) =-3`
`:. ` Phosphorus is oxidised as well as reduced in the reaction.
