Neco 2019 Chemistry Question 46
Practice objective / multiple choice question 46 from the 2019 Neco Chemistry examination.
During analysis, a 2.00 g sample containing only Fe2O3 and Fe3O4 is dissolved in acid and the resulting solution is titrated with 0.0250 M KMnO4 in acidic medium. The titration requires 23.6 mL of the permanganate solution to reach the endpoint. Assuming only Fe^{2+} ions are oxidised by KMnO4, calculate the mass percent of Fe3O4 in the original sample.
