Mercury batteries use either pure mercury(II) oxide (HgO)—also called mercuric oxide—or a mixture of HgO with manganese dioxide (MnO2) as the cathode. Mercuric oxide is a non-conductor, so some graphite is mixed with it; the graphite also helps prevent collection of mercury into large droplets. The half-reaction at the cathode is: with a standard potential of +0.0977 V. WebZn(Hg)+HgO(s)→ZnO(s)+Hg(l) The cell potential remains constant during its life as the overall reaction does not involve any ion in the solution whose concentration may change during its life time. Reason is a factual statement. It's not the correct explanation for the assertion. Hence, option B is correct.
