Gce Model Questions Vol1 2024 Chemistry Question 1
Practice objective / multiple choice question 1 from the 2024 Gce Model Questions Vol1 Chemistry examination.
A 0.500 g sample of \(\mathrm{FeSO_4\cdot7H_2O}\) (M = 278.01 g mol⁻¹) is dissolved in 250 cm³ of water to give a \(\mathrm{Fe^{2+}}\) solution. Exactly 25.0 cm³ of this solution is titrated with an acidified potassium‑permanganate solution. The titration reaches the endpoint after 30.0 cm³ of the permanganate solution. The permanganate solution was prepared by dissolving \(x\) g of \(\mathrm{KMnO_4}\) (M = 158.04 g mol⁻¹) in 500 cm³ of water. Calculate \(x\).
