Neco 2025 Chemistry Question 29
Practice objective / multiple choice question 29 from the 2025 Neco Chemistry examination.
A galvanic cell is constructed with a zinc electrode immersed in 0.100\,M ZnSO\(_4\) solution and a copper electrode immersed in a solution of Cu\(^{2+}\) of unknown concentration. At 25\,°C the cell emf is measured to be 0.76\,V. Given the standard reduction potentials \(E^\circ(\text{Zn}^{2+}/\text{Zn}) = -0.76\ \text{V}\) and \(E^\circ(\text{Cu}^{2+}/\text{Cu}) = +0.34\ \text{V}\), calculate the concentration of Cu\(^{2+}\) in the copper half‑cell.
