How can the reduction potential of an electrode increased ?

Explanation

To increase the reduction potential of an electrode, we can follow these steps:

### Step 1: Understand the Reduction Reaction
The reduction potential is related to the reaction where a cation (Mn⁺) gains electrons to form a solid (M). This is a reduction process.

### Step 2: Use the Nernst Equation
The Nernst equation relates the reduction potential (E) to the standard reduction potential (E°) and the concentrations of the reactants and products:
\[ E = E^\circ - \frac{RT}{nF} \ln \left( \frac{[Products]}{[Reactants]} \right) \]
