Oxidation-reduction potential is the potential (voltage) at which oxidation occurs at the anode (positive) and reduction occurs at the cathode (negative) of an electrochemical cell. In simple terms, from a microbial perspective, an oxidizing chemical pulls electrons away from the cell membrane, causing it to become desta-bilized and leaky.Oxidation-Reduction Potentials One way to quantify whether a substance is a strong oxidizing agent or a strong reducing agent is to use the oxidation-reduction potential or redox potential. Strong reducing agents can be said to have a high electron-transfer potential. Strong oxidizing agents have low electron-transfer potential. The half-reaction and oxidation potential.
