Vedclass · Answer

(D) The reaction between $KMnO_4$ and oxalic acid $(H_2C_2O_4)$ in the presence of dilute $H_2SO_4$ is given by the equation: $2KMnO_4 + 3H_2SO_4 + 5H_2C_2O_4 \rightarrow K_2SO_4 + 2MnSO_4 + 8H_2O + 10CO_2$. In this reaction,$Mn^{2+}$ ions are produced as a product. These $Mn^{2+}$ ions act as an autocatalyst,meaning they increase the rate of the reaction as the reaction proceeds. Therefore,$MnSO_4$ (which provides $Mn^{2+}$ ions) acts as the autocatalyst.

Which one of the following acts as an autocatalyst during the titration of $KMnO_4$ and oxalic acid in the presence of dilute $H_2SO_4$?
