Neco Model Questions Vol1 2024 Chemistry Question 49
Practice objective / multiple choice question 49 from the 2024 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed with a zinc electrode immersed in 0.10 M \(\mathrm{ZnSO_4}\) solution and a copper electrode immersed in an aqueous solution of \(\mathrm{CuSO_4}\) of unknown concentration. At \(25^{\circ}\mathrm{C}\) the cell emf is measured to be \(1.10\ \text{V}\). The standard reduction potentials are \(E^{\circ}_{\mathrm{Cu^{2+}/Cu}} = +0.34\ \text{V}\) and \(E^{\circ}_{\mathrm{Zn^{2+}/Zn}} = -0.76\ \text{V}\).\n\n(a) Calculate the concentration of \(\mathrm{Cu^{2+}}\) ions in the copper half‑cell.\n(b) If a charge of \(0.500\ \text{C}\) passes through the cell, how many grams of copper are deposited on the copper electrode?
