Answer:

The standard oxidation potential measures the tendency for a given chemical species to beoxidized as opposed to be reduced. ... A standard reductionpotential is measured using a galvanic cell which contains a SHE on one side and an unknown chemical half cell on the other side.

Explanation:

In electrochemistry, the Nernst equation is anequation that relates the reduction potential of an electrochemical reaction (half-cell or full cell reaction) to the standard electrode potential, temperature, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation .

The tendency for a species to be oxidized at standard conditions is called the Standard Oxidation Potential.

  • Nernst Equation For Oxidation Electrode is given as follows:

      E_{cell} = E^o _{cell} - \frac{RT}{nF}logQ

      At 25^{0}C this equation can be written as,

      E_{cell} = E^o _{cell} - \frac{0.0591}{n}logQ

  • The above equation states that the electrical potential of an electrode depends upon the reaction quotient Q of the reaction.
