Igcse Model Questions Vol1 2020 Chemistry Question 8
Practice objective / multiple choice question 8 from the 2020 Igcse Model Questions Vol1 Chemistry examination.
A galvanic cell is set up as follows: Zn|Zn^{2+} (0.010 M)||Cu^{2+} (0.10 M)|Cu at 25°C. Standard reduction potentials are: \(\text{Cu}^{2+}+2e^{-}\rightarrow\text{Cu}\) \(E^{\circ}=+0.34\,\text{V}\) and \(\text{Zn}^{2+}+2e^{-}\rightarrow\text{Zn}\) \(E^{\circ}=-0.76\,\text{V}\).\n(a) Calculate the cell EMF under the given concentrations.\n(b) If the concentration of Zn^{2+} is increased to 0.10 M (Cu^{2+} remains 0.10 M), what is the new cell EMF?
