Question

Reaction	E0/V
Ag →Ag+ + e–	–0.80
Cr3+ + 3e– →3Cr	–0.74
Zn2++ 2e– →Zn	0.76
I2(s) + 2e– →2 I–	0.54
Co2+ + 2e– →Co	–0.28
Ni2+ + 2e–→Ni	–0.26

The best reducing agent among the following is 

(A) Ag⁺ 

(B) Zn²⁺ 

(C) Cr³⁺ 

(D) I^–

Answer 1

Correct answer is (D) r^–

Ag⁺,Zn²⁺,Cr³⁺ are not reducing agents.

I^– Is a reducing agent.
