Hydrogen overpotential on mercury - Big Chemical Encyclopedia

Web7 mei 2016 · In the case of hydrogen reduction on mercury, the kinetics is so slow that you need a huge amount of overpotential to get it to go at a reasonable rate. That overpotential is enough to make sodium reduction possible too, and the sodium reduction is kinetically faster. If you use a platinum electrode instead, that does not happen. Webother hand, the lower the overpotential the slower the reaction will occur, so we have to make a compromise. One of the best ways to increase the current without increasing the overpotential is to increase the contact areas between the electrodes and the liquid [2]. 3.
