Electrochemistry:

Electrochemistry is the field of chemistry which deals with the results in the generation of an electric current (electricity) or be caused by imposing an electric current. Electron transfer reactions are oxidation-reduction or redox reactions. In other words "the study of interchange of chemical and electrical energy is Electrochemistry". Electrochemistry can be divided in two categories:

1. Use of electrical energy to produce chemical changes which is known as Electrolysis, and
2. Conversion of chemical energy into electrical energy (by spontaneous redox reactions).

Electrolysis is used in determination of equivalent mass of elements, electroplating of metal and manufacturing of compounds.

Electrochemical series is the arrangement of the electrodes (metal or non-metals) with contact with their ions on the basis of their standard reduction potentials or oxidation potentials.

It is used for designing cells and balancing redox reactions.
