Gce Model Questions Vol1 2025 Chemistry Question 17
Practice objective / multiple choice question 17 from the 2025 Gce Model Questions Vol1 Chemistry examination.
A piece of zinc metal is placed in an aqueous solution containing \(0.10\ \text{mol}\) of \(\text{Fe}^{3+}\) and \(0.15\ \text{mol}\) of \(\text{Cu}^{2+}\). Standard reduction potentials are: \(\text{Zn}^{2+}/\text{Zn} = -0.76\ \text{V}\), \(\text{Fe}^{3+}/\text{Fe}^{2+} = +0.77\ \text{V}\), \(\text{Cu}^{2+}/\text{Cu} = +0.34\ \text{V}\). Assuming the reactions proceed spontaneously, which ion is reduced first? Then calculate the maximum mass of copper that can be deposited after all \(\text{Fe}^{3+}\) has been reduced.
