In the reaction `Pb(s)+Cu^(2+) (aq) rarr Pb^(2+) (aq)+Cu(s)` which is reducing agent

A

`Pb^(2+) (aq)`

B

`Cu^(2+) (aq)`

C

`Pb(s)`

D

`Cu(s)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Pb_((s))` releases `2e^(-)` to form `Pb_((aq))^(2+)` and its O.N. increases by 2, hence it is a reducing agent.
