Gce Model Questions Vol1 2023 Chemistry Question 27
Practice objective / multiple choice question 27 from the 2023 Gce Model Questions Vol1 Chemistry examination.
A galvanic cell consists of a zinc electrode immersed in a 0.010 M \(\mathrm{Zn^{2+}}\) solution and a copper electrode immersed in a 0.10 M \(\mathrm{Cu^{2+}}\) solution at 25 °C. Standard electrode potentials are \(E^{\circ}(\mathrm{Zn^{2+}/Zn}) = -0.76\) V and \(E^{\circ}(\mathrm{Cu^{2+}/Cu}) = +0.34\) V.\n\n(a) Calculate the cell potential at 25 °C.\n(b) If the cell operates until 0.025 mol of zinc is oxidised, determine (i) the total charge passed (in coulombs) and (ii) the mass of copper deposited on the copper electrode (in grams).
