Neco Model Questions Vol1 2024 Chemistry Question 45
Practice objective / multiple choice question 45 from the 2024 Neco Model Questions Vol1 Chemistry examination.
In acidic solution the redox reaction between permanganate ion and ferrous ion proceeds as: \[\mathrm{MnO_4^- + Fe^{2+} \rightarrow Mn^{2+} + Fe^{3+}}.\] The standard reduction potentials are E°_{MnO_4^- / Mn^{2+}} = +1.51 V and E°_{Fe^{3+} / Fe^{2+}} = +0.77 V. The solution contains [MnO_4^-] = 0.010 M, [Fe^{2+}] = 0.10 M and [Fe^{3+}] = 0.020 M at 25 °C. Assuming the concentration of Mn^{2+} is negligible initially, calculate the cell potential E using the Nernst equation.
