Negative reduction potential
Aug 29, 2023 · It is possible to construct a cell that does work on a chemical system by driving an electric current through the system. These cells are called electrolytic cells. Electrolytic cells, like galvanic cells, are composed of two half-cells--one is a reduction half-cell, the other is an oxidation half-cell. The equation that you give 'E Cell = (More Positive E Potential) - (Less Positive E potential)' only works if the less positive E potential is the reducing agent and the more positive E potential is the oxidizing agent, when the reducing agent is negative, and you haven't switched the sign. this 'E Cell = (More Positive E Potential) - (Less Positive E potential)' works only in these select cases.
