Vedclass · Answer

(A) The chemical equation for the preparation of chlorine is: $MnO_2 + 4HCl \rightarrow MnCl_2 + 2H_2O + Cl_2$. In this reaction,the oxidation state of $Mn$ changes from $+4$ in $MnO_2$ to $+2$ in $MnCl_2$. Since the oxidation state of $Mn$ decreases,$MnO_2$ undergoes reduction. $A$ substance that undergoes reduction acts as an oxidising agent. Therefore,$MnO_2$ acts as an oxidising agent.

In the preparation of chlorine from $HCl,$ $MnO_2$ acts as
