Gce Model Questions Vol1 2020 Chemistry Question 2
Practice objective / multiple choice question 2 from the 2020 Gce Model Questions Vol1 Chemistry examination.
A galvanic cell is set up with a zinc electrode immersed in a 0.010 M Zn²⁺ solution and a copper electrode immersed in a 0.10 M Cu²⁺ solution 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\n(a) Calculate the cell EMF under these conditions using the Nernst equation.\n(b) If the cell delivers a constant current of 0.50 A for 2.0 h, how much copper (in grams) is deposited on the copper electrode?
