CBSE Class 12 Chemistry Chapter 3 - Electrochemistry Notes

Electrochemistry Class 12 CBSE Revision Notes

This article deals with electrochemistry notes. First of all, electrochemistry deals with the production of electricity from energy. Furthermore, the release of this energy takes place during spontaneous chemical reactions. The chapter is certainly of paramount importance for both practical as well as theoretical considerations. Most noteworthy, the production of a huge number of chemicals and metals happens by electrochemical methods. The conversion of chemical energy into electrical energy takes place due to batteries and fuel cells.

The reactions which result from electrochemical processes are both energy efficient and less polluting. Consequently, electrochemistry notes help in new innovative technologies that are eco-friendly in nature. Furthermore, electrochemistry enables the transmission of sensory signals from the cells to the brain and vice-versa. Electrochemistry is, without a shred of doubt, a very vast and interdisciplinary topic that has huge implications in the field of chemistry.
