The standard reduction potentials of Cu2+ / CuandCu2+ / Cu+are 0.337 V...
To determine the standard electrode potential of the Cu/Cu half-cell, we need to consider the reduction half-reaction for the Cu2/Cu couple and the oxidation half-reaction for the Cu/Cu2 couple.
The reduction half-reaction for the Cu2/Cu couple can be written as follows:
Cu2+ + 2e- -> Cu
The standard reduction potential for this half-reaction is given as 0.337 V.
The oxidation half-reaction for the Cu/Cu2 couple can be written as follows:
Cu -> Cu2+ + 2e-
The standard reduction potential for this half-reaction is given as -0.153 V.
To determine the standard electrode potential for the Cu/Cu half-cell, we need to reverse the sign of the standard reduction potential for the oxidation half-reaction. Therefore, the standard electrode potential for the Cu/Cu half-cell is +0.153 V (since -(-0.153) = +0.153 V).
Hence, the correct answer is option 'C' (0.521 V).
In summary:
- Reduction half-reaction for Cu2/Cu couple: Cu2+ + 2e- -> Cu (E° = 0.337 V)
- Oxidation half-reaction for Cu/Cu2 couple: Cu -> Cu2+ + 2e- (E° = -0.153 V)
- Standard electrode potential for Cu/Cu half-cell: +0.153 V
Therefore, the correct answer is option 'C' (0.521 V).
The reduction half-reaction for the Cu2/Cu couple can be written as follows:
Cu2+ + 2e- -> Cu
The standard reduction potential for this half-reaction is given as 0.337 V.
The oxidation half-reaction for the Cu/Cu2 couple can be written as follows:
Cu -> Cu2+ + 2e-
The standard reduction potential for this half-reaction is given as -0.153 V.

Hence, the correct answer is option 'C' (0.521 V).
In summary:
- Reduction half-reaction for Cu2/Cu couple: Cu2+ + 2e- -> Cu (E° = 0.337 V)
- Oxidation half-reaction for Cu/Cu2 couple: Cu -> Cu2+ + 2e- (E° = -0.153 V)
- Standard electrode potential for Cu/Cu half-cell: +0.153 V
Therefore, the correct answer is option 'C' (0.521 V).
