Calculation of Standard Electrode Potential
The standard electrode potential is the measure of the tendency of a half-cell to gain or lose electrons. It is measured with respect to a standard hydrogen electrode (SHE). The standard reduction potentials of Cu2 | Cu and Cu2 |Cu are given as:
- Cu2+ + 2e- → Cu E° = 0.337 V
- Cu2+ + 2e- ← Cu E° = -0.153 V
To calculate the standard electrode potential of Cu | Cu half-cell, we need to use the formula:
E°cell = E°reduction (reduced form) - E°reduction (oxidized form)
Substituting the given values, we get:
E°cell = 0.337 - (-0.153) = 0.490 V
So, the standard electrode potential of Cu | Cu half-cell is 0.490 V.
Answer and Explanation
The given options are:
a) 0.184 V
b) 0.827 V
c) 0.521 V
d) 0.490 V
The correct option is (c) 0.521 V. This is the standard electrode potential of Cu | Cu half-cell calculated using the given standard reduction potentials of Cu2 | Cu and Cu2 |Cu. Option (a) is incorrect as it is not equal to the calculated value. Option (b) is incorrect as it is much higher than the calculated value. Option (d) is incorrect as it is equal to the standard reduction potential of Cu2 | Cu half-cell, which is not the same as the standard electrode potential of Cu | Cu half-cell.

E°cell = E°reduction (reduced form) - E°reduction (oxidized form)
Substituting the given values, we get:
E°cell = 0.337 - (-0.153) = 0.490 V
So, the standard electrode potential of Cu | Cu half-cell is 0.490 V.
Answer and Explanation
The given options are:
a) 0.184 V
b) 0.827 V
c) 0.521 V
d) 0.490 V
The correct option is (c) 0.521 V. This is the standard electrode potential of Cu | Cu half-cell calculated using the given standard reduction potentials of Cu2 | Cu and Cu2 |Cu. Option (a) is incorrect as it is not equal to the calculated value. Option (b) is incorrect as it is much higher than the calculated value. Option (d) is incorrect as it is equal to the standard reduction potential of Cu2 | Cu half-cell, which is not the same as the standard electrode potential of Cu | Cu half-cell.
