Question

What is standard reduction potential?

Answer 1

1. In the process of reduction, gain of electrons occur and therefore the tendency of gaining the electrons is so-called reduction potential.
2. It is impossible to calculate the electrode potential of the single-cell therefore the potential difference needs to be calculated.
3. The electrode potential of the cell is calculated with the help of a reference electrode.
4. The electrode potential of cell is calculated as follows:${\mathrm{E}}_{\mathrm{cell}}={\mathrm{E}}_{\mathrm{anode}}+{\mathrm{E}}_{\mathrm{cathode}}$.
5. In a solution if we immerse a metal piece of its own ions, a potential difference is developed at the interface of a metal and the dipped solution.
6. The potential is developed because of the reaction occurring on the metal surface, and so the solution is called electrode potential. The tendency of electrode potential to lose or gain electrons is called oxidation and reduction potential respectively.
7. Reduction if occurs on the electrode then it is called reduction potential and chemically represented as follows:
   ${\mathrm{M}}^{2+}+2{\mathrm{e}}^{-}\to \mathrm{M}$
