Gce Model Questions Vol1 2017 Chemistry Question 4
Practice objective / multiple choice question 4 from the 2017 Gce Model Questions Vol1 Chemistry examination.
In an acidic solution, potassium permanganate (KMnO₄) reacts with excess ferrous ions (Fe²⁺) according to the balanced equation: MnO₄⁻ + 5 Fe²⁺ + 8 H⁺ → Mn²⁺ + 5 Fe³⁺ + 4 H₂O. If 10.0 g of KMnO₄ is used, calculate the mass of Fe³⁺ ions formed. (Atomic masses: K = 39.10, Mn = 54.94, O = 16.00, Fe = 55.85, H = 1.01). Give your answer to three significant figures.
