Introduction of Electrochemistry. Electrochemistry is a field of chemistry that studies chemical reactions which take place at the interface of an electron conductor a metal or a semiconductor and an ionic conductor the electrolyte in a solution, and that involve electron transfer among the electrode and the electrolyte or species in solution. It is an electrochemical reaction when, By an external applied voltage if a chemical reaction is driven, like in electrolysis or by a chemical reaction if a voltage is created like in a battery. Redox reactions: for reduction-oxidation we use Redox and are electrochemical processes involving transfer of electron to or from a molecule or ion changing its oxidation state. From the application of an external voltage or from the release of chemical energy this reaction can take place.

Electrochemistry deals with chemical reactions that produce electricity and the changes associated with the passage of electrical current through matter. The reactions involve electron transfer, and so they are oxidation-reduction or redox reactions. Many metals may be purified or electroplated using electrochemical methods. Devices such as automobiles, smartphones, electronic tablets, watches, pacemakers, and many others use batteries for power. Batteries use chemical reactions that produce electricity spontaneously and that can be converted into useful work.
