Question

What do you mean by redox reaction ? Explain with the help of an example.

Answer 1

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. 

Answer 2

A redox reaction is defined as a reaction in which oxidation and reduction take place simultaneously. In fact, both these processes take place simultaneously.

For example in the reaction of Copper oxide and Hydrogen.

In the above process.

1. Removal of oxygen from copper oxide to form copper.

2. Addition of oxygen to hydrogen to form water.
