`M^(n+)(aq)+n e^(-)rarrM(s)`

Text Solution

AI Generated Solution

To increase the reduction potential of an electrode for the reaction \( M^{n+}(aq) + n e^- \rightarrow M(s) \), we can follow these steps based on the Nernst equation. ### Step-by-Step Solution: 1. **Understand the Nernst Equation**: The Nernst equation is given by: \[ E = E^\circ - \frac{2.303RT}{nF} \log \left( \frac{[\text{Products}]}{[\text{Reactants}]} \right) ...
