Neco Model Questions Vol1 2020 Chemistry Question 20
Practice objective / multiple choice question 20 from the 2020 Neco Model Questions Vol1 Chemistry examination.
In acidic solution the redox reaction between permanganate ion and oxalic acid is balanced as follows: \( \text{MnO}_4^- + \text{C}_2\text{O}_4^{2-} + H^+ \rightarrow \text{Mn}^{2+} + CO_2 + H_2O \). (i) Balance the overall redox equation, showing the stoichiometric coefficients. (ii) If 0.0250 mol of KMnO₄ reacts completely with excess oxalic acid, calculate the volume of 0.500 M H₂SO₄ required to supply the necessary H⁺ ions.
