Vedclass · Answer

(C) The reaction between oxalic acid $(H_2C_2O_4)$ and acidified potassium permanganate $(KMnO_4)$ is slow at room temperature. As the reaction proceeds,$Mn^{2+}$ ions are produced. These $Mn^{2+}$ ions act as a catalyst for the reaction,increasing its rate. Since the product of the reaction itself acts as a catalyst,this phenomenon is known as autocatalysis,and the substance is called an autocatalyst.

In the titration between oxalic acid and acidified potassium permanganate,the manganous salt formed catalyses the reaction. The manganous salt is
