Neco Model Questions Vol1 2017 Chemistry Question 6
Practice objective / multiple choice question 6 from the 2017 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Zn(s) | Zn^{2+}(0.010\,M) || Cu^{2+}(0.050\,M) | Cu(s) at 25\(^\circ\)C. Standard reduction potentials are E°(Zn^{2+}/Zn) = -0.76\,V and E°(Cu^{2+}/Cu) = +0.34\,V. (a) Calculate the cell EMF under the given concentrations using the Nernst equation. (b) If the cell delivers a total charge of 0.500\,C, how many grams of copper are deposited on the copper electrode?
