Igcse Model Questions Vol1 2023 Chemistry Question 22
Practice objective / multiple choice question 22 from the 2023 Igcse Model Questions Vol1 Chemistry examination.
In acidic solution the redox reaction between potassium permanganate and oxalic acid is: \(\mathrm{KMnO_4}\) + \(\mathrm{C_2O_4^{2-}}\) → \(\mathrm{Mn^{2+}}\) + \(\mathrm{CO_2}\). A sample of 0.50 g \(\mathrm{KMnO_4}\) is mixed with excess oxalic acid and enough 0.10 M \(\mathrm{H_2SO_4}\) to provide the required acidity. (a) Calculate the volume of \(\mathrm{H_2SO_4}\) solution needed. (b) Calculate the mass of \(\mathrm{CO_2}\) produced.
