Vedclass · Answer

(C) Step $1$: $A$ mercury battery is a primary cell that uses a $Zn$ anode and a $HgO$ cathode.Step $2$: The electrolyte used is a paste of $KOH$ and $ZnO$, which is strongly alkaline (basic), not acidic.Step $3$: The cell reaction at the cathode is $HgO(s) + H_2O(l) + 2e^- \rightarrow Hg(l) + 2OH^-(aq)$, where $HgO$ is reduced to $Hg$.Step $4$: Since the electrolyte is basic, the statement that it is strongly acidic is false.
