Electrochemistry is the study of production ofelectricity from energy released during spontaneouschemical reactions and the use of electrical energyto bring about non-spontaneous chemicaltransformations. The subject is of importance bothfor theoretical and practical considerations. A largenumber of metals, sodium hydroxide, chlorine,fluorine and many other chemicals are produced byelectrochemical methods. Batteries and fuel cellsconvert chemical energy into electrical energy and areused on a large scale in various instruments anddevices. The reactions carried out electrochemicallycan be energy efficient and less polluting.
Chemistry 66 The potential difference between the two electrodes of a galvanic cell is called the cell potential and is measured in volts. The cell potential is the difference between the electrode potentials (reduction potentials) of the cathode and anode.
