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. WebMercury oxide is stored in the cathode of a mercury cell, so the value of +0.0977 V given in the problem is the cathode’s electrode potential. Using this value and the cell potential, we will solve for the anode’s electrode reduction potential.
