Amount of oxalic acid present in a solution can be determined by its titration with KMnO4, solution in the presence of H2SO4 .

Question 1

Amount of oxalic acid present in a solution can be determined by its titration with KMnO4, solution in the presence of H2SO4 . The titration gives unsatisfactory result when carried out in the presence of HCl because HCl

(a) gets oxidised by oxalic acid to chlorine

(b) furnishes H+ ions in addition to those from oxalic acid

(c) reduces permanganate to Mn2+

(d) oxidises oxalic acid to carbon dioxide and water

Question 2

Correct option (c) reduces permanganate to Mn2+

Explanation:

Titration of oxalic acid by KMnO4 in the presence of HCI gives an unsatisfactory result because HCI is a better reducing agent than oxalic acid and HCI reduces preferably MnO4- to Mn2+.
