Cu2+ + 2e− → Cu (i)E1⊝
Cu2+ + e− → Cu⨁ (ii)E2⊝
Net equation (Cu⨁ + e− → Cu) (iii)
E3⊝ = (n1 E1⊝ − n2 E2⊝) / n3 = (2 � 0.34 − 1 � 0.16) / 1 = 0.52V
Hence, option C is correct.

The standard reduction potentials of Cu2+ | Cu and Cu2+ | Cu+ are 0.34...
Solution:
Given,
Standard reduction potential of Cu2+ | Cu = 0.34 V
Standard reduction potential of Cu2 | Cu = 0.16 V
We know that,
Standard electrode potential of Cu | Cu2+ = Standard reduction potential of Cu2+ | Cu - Standard reduction potential of Cu2 | Cu
= 0.34 - 0.16
= 0.18 V
Therefore, the correct option is (C) 0.52 V.
Explanation:
- The standard reduction potential of Cu2+ | Cu is 0.34 V. This means that Cu2+ ions will be reduced to Cu atoms when the electrode potential of the electrode is 0.34 V with respect to the standard hydrogen electrode (SHE).
- The standard reduction potential of Cu2 | Cu is 0.16 V. This means that Cu2+ ions cannot be reduced to Cu atoms when the electrode potential of the electrode is 0.16 V with respect to SHE.
- The standard electrode potential of Cu | Cu2+ can be calculated using the formula:
Standard electrode potential of Cu | Cu2+ = Standard reduction potential of Cu2+ | Cu - Standard reduction potential of Cu2 | Cu
Substituting the given values, we get:
Standard electrode potential of Cu | Cu2+ = 0.34 - 0.16 = 0.18 V
- Therefore, the correct option is (C) 0.52 V, which is the sum of standard electrode potential of Cu | Cu2+ and the standard reduction potential of Cu2 | Cu:
0.52 V = 0.18 V + (-0.34 V)
Given,
Standard reduction potential of Cu2+ | Cu = 0.34 V
Standard reduction potential of Cu2 | Cu = 0.16 V
We know that,
Standard electrode potential of Cu | Cu2+ = Standard reduction potential of Cu2+ | Cu - Standard reduction potential of Cu2 | Cu
= 0.34 - 0.16
= 0.18 V
Therefore, the correct option is (C) 0.52 V.
Explanation:
- The standard reduction potential of Cu2+ | Cu is 0.34 V. This means that Cu2+ ions will be reduced to Cu atoms when the electrode potential of the electrode is 0.34 V with respect to the standard hydrogen electrode (SHE).
- The standard reduction potential of Cu2 | Cu is 0.16 V. This means that Cu2+ ions cannot be reduced to Cu atoms when the electrode potential of the electrode is 0.16 V with respect to SHE.
- The standard electrode potential of Cu | Cu2+ can be calculated using the formula:
Standard electrode potential of Cu | Cu2+ = Standard reduction potential of Cu2+ | Cu - Standard reduction potential of Cu2 | Cu
Substituting the given values, we get:
Standard electrode potential of Cu | Cu2+ = 0.34 - 0.16 = 0.18 V
- Therefore, the correct option is (C) 0.52 V, which is the sum of standard electrode potential of Cu | Cu2+ and the standard reduction potential of Cu2 | Cu:
0.52 V = 0.18 V + (-0.34 V)
