Question

Given below are two statements: Statement I: In the oxalic acid vs $KMnO_{4}$ (in the presence of dil $H_{2} SO_{4}$ ) titration the solution needs to be heated initially to $6 0^{\circ} C$ , but no heating is required in Ferrous ammonium sulphate (FAS) vs $KMnO_{4}$ titration (in the presence of dil $H_{2} SO_{4}$ ) 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

Options:

Answer:

B

Solution:

Heating is required in oxalic acid filtration due to High activation energy. Heating is not required in FAS vs $KMnO_{4}$ titration because $Fe^{2 +}$ will get converted into $Fe^{3 +}$ by oxygen of air and error may be introduced in the experiment. Both Statement-I and Statement-II are correct.
