Hint: An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
Complete step by step answer:
Redox reactions are oxidation-reduction chemical reactions in which the reactants undergo a change in their oxidation states. The term ‘redox’ is a short form of reduction-oxidation. All the redox reactions can be broken down into two different processes – a reduction process and an oxidation process.
The oxidation and reduction reactions always occur simultaneously.
What is an oxidizing and reducing agent?
The substance getting reduced in a chemical reaction is known as the oxidizing agent, while a substance that is getting oxidized is known as the reducing agent.
There are majorly 4 types of redox reactions
Decomposition Reaction
Combination Reaction
Displacement Reaction
Disproportionation Reaction
Example of a redox reaction between Zinc and Copper.
The reaction that takes place between zinc and copper is metal displacement reaction. Where copper metal is obtained when zinc displaces the ion in the copper sulphate solution as shown in the reaction below.
We write 2 parts in an redox reaction oxidation half reaction and reduction half reaction . so here are the following:-
The oxidation half-reaction can be written as:
The reduction half-reaction can be written as:
Note: Oxidation-reduction (redox) reactions are important because they are the principal sources of energy on this planet, both natural or biological and artificial. Oxidation of molecules by removal of hydrogen or combination with oxygen normally liberates large quantities of energy.
