Given below are two statements : Statement I : In the oxalic acid vs KMnO4 (in the presence of dil H2SO4) titration the solution needs to be heated initially to 60°C, but no heating is required in Ferrous ammonium sulphate (FAS) vs KMnO4 titration (in the presence of dil H2SO4) Statement I

Question

Given below are two statements : Statement I : In the oxalic acid vs KMnO4 (in the presence of dil H2SO4) titration the solution needs to be heated initially to 60°C, but no heating is required in Ferrous ammonium sulphate (FAS) vs KMnO4 titration (in the presence of dil H2SO4) Statement II : In oxalic acid vs KMnO4 titration, the initial formation of MnSO4 takes place at high temperature, which then acts as catalyst for further reaction. In the case of FAS vs KMnO4, heating oxidizes Fe2+ into Fe3+ by oxygen of air and error may be introduced in the experiment. In the light of the above statements, choose the correct answer from the options given below :

Accepted Answer

Both Statement I and Statement II are true. Both statements accurately describe the conditions and reactions involved in the titrations. Statement I correctly notes the need for heating in the oxalic acid titration to facilitate the reaction, while Statement II explains the catalytic role of MnSO4 at high temperatures and the potential errors introduced in the FAS titration due to oxidation of Fe2+.
