Free energy change expressed as oxidation-reduction or redox potential. In acid medium H + ions and water are added to half-reactions to balance the overall reaction. Involve a transfer of electrons between reacting species. A redox reaction is feasible only if the species which has higher potential is reduced i.e., accepts the electrons and the species which has lower reduction potential is oxidized i.e., loses electrons. The electron transfer system in cells and oxidation of glucose in the human body are examples of redox reactions. Here, the electrochemical cell is explained for redox‐active ions, introducing a new comparison between the measurement of midpoint potential and the measurement of initial velocity for enzymes.
