Gce Model Questions Vol1 2021 Chemistry Question 30
Practice objective / multiple choice question 30 from the 2021 Gce Model Questions Vol1 Chemistry examination.
In an acidic solution, potassium permanganate reacts with ferrous ions according to \(\mathrm{MnO_4^- + 5 Fe^{2+} \rightarrow Mn^{2+} + 5 Fe^{3+}}\). A \(25.0\ \mathrm{mL}\) sample of \(0.200\ \mathrm{M}\) \(\mathrm{KMnO_4}\) is mixed with excess \(\mathrm{Fe^{2+}}\). After the reaction, \(10.0\ \mathrm{mL}\) of the solution is titrated and found to contain \(0.150\ \mathrm{M}\) unreacted \(\mathrm{Fe^{2+}}\). Calculate the mass of \(\mathrm{Fe^{3+}}\) formed (in grams).
