Question 53

Medium

What is the minimum volume, in $cm3\text{cm}^3$ , of 0.025 mol dm^-3 potassium manganate(VII) ( $KMnO4\text{KMnO}_4$ ) solution needed to completely oxidise 0.015 mol of ethanedioate ions ( $C2O42−\text{C}_2\text{O}_4^{2-}$ )?

2\text{MnO}_4^- + 5\text{C}_2\text{O}_4^{2-} + 16\text{H}^+ \rightarrow 2\text{Mn}^{2+} + 10\text{CO}_2 + 8\text{H}_2\text{O}
