Question

Describe briefly the ionic concept of oxidation and reduction. Give an equation to illustrate.​

Answer 1

Oxidation: ​ ​
The process in which an element donate electrons is known as oxidation. ​ ​
The oxidation state of an atom or ion increases due to oxidation.​ ​ Example:
$Zn\to Zn{{}^2}^{+}+2e^{-}$

​ Reduction:​ ​
The process in which an element gains electron is called reduction.​ ​
The oxidation state of an atom or ion decreases due to reduction.​ ​
Example:
$Cu{{}^2}^{+}+2e^{-}\to Cu$
