Neco Model Questions Vol1 2020 Chemistry Question 23
Practice objective / multiple choice question 23 from the 2020 Neco Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as \(\mathrm{Zn|Zn^{2+}(unknown)}\) || \(\mathrm{Cu^{2+}(0.010\,M)|Cu}\). At 25 °C the measured emf is \(1.05\) V. Standard electrode potentials are \(E^{\circ}(\mathrm{Zn^{2+}/Zn}) = -0.76\) V and \(E^{\circ}(\mathrm{Cu^{2+}/Cu}) = +0.34\) V. Calculate the concentration of \(\mathrm{Zn^{2+}}\) in the cell.
