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 0.00V` respectively. Choose the strongest reducing agent amogn the following

A

`Zn`

B

`H_(2)`

C

`Ag`

D

`Li`

Text Solution

Verified by Experts

The correct Answer is:
D
More the negative reduction potential, more is the tendency to lose electron. The reducing power increases as the standard reduction potential becomes more and more negative.
Thus, Li is the strongest reducing agent as the standard reduction potential of `Li^(+)//Li` is most negative, -3.05 V
