Given below are two statements:
Statement I: In the oxalic acid vs KMnO
4 (in the presence of dil H
2SO
4) titration the solution needs to be heated initially to 60°C, but no heating is required in Ferrous ammonium sulphate (FAS) vs KMnO
4 titration (in the presence of dil H
2SO
4).
Statement II: In oxalic acid vs KMnO
4 titration, the initial formation of MnSO
4 takes place at high temperature, which then acts as catalyst for further reaction. In the case of FAS vs KMnO
4, heating oxidizes Fe
2+ into Fe
3+ 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:
