To calculate the reduction potential for the copper couple \( \text{Cu}^{2+}/\text{Cu} \) at \( \text{pH} = 14 \), we will follow these steps: ### Step 1: Understand the given data We know the standard reduction potential \( E^\circ \) for the reaction \( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \) is \( +0.34 \, \text{V} \). We also have the solubility product \( K_{sp} \) of \( \text{Cu(OH)}_2 \) as \( 1.0 \times 10^{-19} \). ### Step 2: Calculate the concentration of hydroxide ions At \( \text{pH} = 14 \): \[ ...
