Electrochemistry involves the study of chemical reactions involving electricity from "summary" of Chemistry Simplified NCERT Class 11 by Sanjay Sharma
Electrochemistry is a branch of chemistry that deals with the study of chemical reactions involving electricity. This means that it focuses on how chemical reactions can be influenced by the presence of an electric current. In simpler terms, it is the study of how electricity can be used to drive or facilitate chemical reactions. One important concept in electrochemistry is that of redox reactions. These are reactions where there is a transfer of electrons between reactants. The reactant that loses electrons is said to be oxidized, while the reactant that gains electrons is said to be reduced. This is where the term "redox" comes from - it is a combination of "reduction" and "oxidation." In electrochemical reactions, electrons are transferred between different species through an external circuit. This transfer of electrons generates an electric current, which can be used to do work. For example, a battery is a device that uses electrochemical reactions to produce a flow of electric current. Electrochemistry also plays a crucial role in many industrial processes. For example, electrolysis is a process that uses electricity to drive a chemical reaction that would not occur spontaneously. This process is used to extract metals from their ores, purify metals, and even produce chlorine gas and sodium hydroxide.- Electrochemistry is a fascinating field that explores the intersection of chemistry and electricity. By studying how electricity can influence chemical reactions, scientists have been able to develop new technologies and understand fundamental processes in nature.
