Neco Model Questions Vol1 2025 Chemistry Question 6
Practice objective / multiple choice question 6 from the 2025 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as \(\text{Zn(s)}| \text{Zn}^{2+}(0.010\ \text{M}) \;||\; \text{Cu}^{2+}(0.10\ \text{M})| \text{Cu(s)}\). The standard reduction potentials are \(E^{\circ}_{\text{Zn}^{2+}/\text{Zn}} = -0.76\ \text{V}\) and \(E^{\circ}_{\text{Cu}^{2+}/\text{Cu}} = +0.34\ \text{V}\).\n(a) Calculate the cell potential at 25 °C using the Nernst equation.\n(b) If a total charge of \(0.500\ \text{C}\) passes through the cell, determine the mass of copper deposited on the copper electrode.
