What is electrochemistry ? Explain its application. OR explain: Electrochemistry is wide and interdisciplinary subject.

Explanation

Electrochemistry is the study of production of electricity from energy released during the spontaneous chemical reactions and the use of electrical energy to bring about non-spontaneous chemical transformations.
Applications: Theoretical and practical utilization of electrochemistry is as follows:
(i) Many metals, sodium hydroxide, chlorine, fluorine and many other chemicals are produced by electrochemical methods.
(ii) Batteries and fuel cells convert chemical energy into electrical energy and are used on a large scale in various instruments and devices. the reactions carried out electrochemically are more energy efficient and less polluting.
(iii) Therefore, study of electrochemistry is important for creating new technologies that are ecofriendly.
(iv) The transmission of sensory signals through cells to brain and so vice versa and communication between the cells are known to have electrochemical origin.
Electrochemistry, is therefore, a very vast and interdisciplinary subject.
