The standard reduction potentials for `Cu^(2+)//Cu, Zn^(2+)//Zn, Li^(+)//Li, Ag^(+)//Ag` and `H^(+)//H_(2)` are `0.34V, -0.762V, -3.05V, +0.80V` and 0.00 V respectively . Choose the strongest reducting agent among the following

A

Zn

B

`H_(2)`

C

Ag

D

Li

Text Solution

Verified by Experts

The correct Answer is:
D

Smaller is reduction potential, more is the tendency to get oxidised and stronger is the reducing agent.
