Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice-versa.
These reactions involve electric charges moving between electrodes and an electrolyte (or ionic species in a solution). Thus electrochemistry deals with the interaction between electrical energy and chemical change. When a chemical reaction is caused by an externally supplied current, as in electrolysis, or if an electric current is produced by a spontaneous chemical reaction as in a battery, it is called an electrochemical reaction. Chemical reactions where electrons are transferred directly between molecules and/or atoms are called oxidation-reduction or (redox) reactions. In general, electrochemistry describes the overall reactions when individual redox reactions are separate but connected by an external electric circuit and an intervening electrolyte. Electrochemical reactions involve electrical charges moving between electrodes associate degreed an solution (or ionic species during a solution). so chemistry deals with the interaction between power and action.
When a reaction is caused by associate degree outwardly equipped current, as in electrolysis, or if an electrical current is created by a spontaneous reaction as during a battery, it's known as associate degree chemistry reaction. Chemical reactions wherever electrons area unit transferred directly between molecules and/or atoms area unit known as redox or (redox) reactions. In general, chemistry describes the general reactions once individual oxidoreduction reactions area unit separate however connected by associate degree external electrical circuit associate degreed an intervening solution.
