$Mn^{2+}$ acts as auto catalyst

Vedclass · Answer

Here, $KMnO _4$ is a reactant in the reaction which forms $Mn ^{2+}$ which acts as an auto-catalyst. The reaction is slow initially because $MnO _4{ }^{-}$is getting converted to $Mn ^{2+}$ but once $Mn ^{2+}$ forms, the reaction becomes faster due to the catalytic action.

When $KMnO_4$ solution is added to hot oxalic acid solution, the decolourisation is slow in the beginning but becomes instantaneous after some time. This is because
