What is electrode potential ?
Answers
Explanation:
In electrochemistry, electrode potential is the electromotive force of a galvanic cell built from a standard reference electrode and another electrode to be characterized. By convention, the reference electrode is the standard hydrogen electrode (SHE). It is defined to have a potential of zero volts.

Electrical potential (commonly known as voltage) is the strength of the push or pull on electrons by the reactants in a redox reaction (reaction that involves transfer of electrons).
It is of two types —
- Oxidation potential
- Reduction potential
When electrode is negatively charged with respect to solution that is it acts as anode.The oxidation take place.
When electrode is positively charged with respect to solution that is it acts as cathode.The reduction take place.
