Given that the standard potentials `((E^(@)))` of `CU^(2+)//Cu` and `CU^(+)//Cu` are 0.34V and 0.522V respectively , the `E^(@)` of `CU^(2+)//CU^(+)` is :

Options

A. `(+0.158V)`
B. `(-0.182V)`
C. `(-0.158V)`
D. `(0.182V)`

Explanation

To find the standard potential \( E^\circ \) for the half-reaction \( \text{Cu}^{2+} + e^- \rightarrow \text{Cu}^+ \), we can use the given standard potentials for the half-reactions involving copper ions.

### Step-by-Step Solution:

1. **Identify the given standard potentials:**
- \( E^\circ \) for \( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \) is \( 0.34 \, \text{V} \).
- \( E^\circ \) for \( \text{Cu}^+ + e^- \rightarrow \text{Cu} \) is \( 0.522 \, \text{V} \).
