Question
Explain redox reactions on the basis of electron transfer. Give suitable examples.

Answer


Redox reactions are the reactions in which the oxidation and reduction process are carried out simultaneously i.e. one reactant is getting reduced while the other gets oxidized. Such reactions are called oxidation reduction reactions or redox reactions .
Oxidation- Oxidation is defined as a process that involves a gain of oxygen or a loss of hydrogen and loss of electrons.
Reduction- It is defined as a process that involves gain of hydrogen and electrons and loss of oxygen.
