Neco Model Questions Vol1 2025 Chemistry Question 39
Practice objective / multiple choice question 39 from the 2025 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Zn(s) | Zn²⁺(0.010 M) || Cu²⁺(0.050 M) | Cu(s) at 25 °C. 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 EMF using the Nernst equation.\n(b) State which electrode is the anode and which is the cathode.\n(c) If a total charge of 0.500 C passes through the cell, how many grams of copper are deposited on the copper electrode?
