Can a nickel spoon be used to stir a solution of silver nitrate? Support your answer with reason.
`(E_(Ni^(2+),Ni)^(@)=-0.25V,E_(Ag^(+),Ag)^(@)=+0.80V)`.

Explanation

To determine whether a nickel spoon can be used to stir a solution of silver nitrate, we need to analyze the electrochemical potentials of nickel and silver.

### Step-by-Step Solution:

1. **Identify the Reduction Potentials**:
- The standard reduction potential for nickel (Ni) is given as \( E^\circ_{Ni^{2+}/Ni} = -0.25 \, V \).
- The standard reduction potential for silver (Ag) is given as \( E^\circ_{Ag^{+}/Ag} = +0.80 \, V \).
