Here We are going to discuss What is Chlor alkali process and why it is named so and the reaction involved in this Process
___________________________________
What is Chlor-alkali Process ?
When electricity is passed through an aqueous Solution of Sodium Chloride i.e. Nacl ( called brine) , it decomposes to form Sodium hydroxide
The process is called the Chlor-alkali process
In this process Chlorine gas is given off at the anode
Hydrogen gas at the Cathode
Sodium hydroxide Solution is formed near the cathode
The three product formed in this process i.e. Sodium hydroxide , hydrogen and Chlorine gas are all useful to us
Hydrogen gas at cathode use for fuels and ammonia for fertilisers
While Chlorine gas at anode use for Water treatment , PVC and pesticides
Sodium hydroxide is use for Soaps and Detergents and paper making
If we take reaction between hydrogen and Chlorine it also formed a product is useful
Hydrochloric acid is use for Cleaning Steel , Medicines etc .
If We take Sodium hydroxide and Chlorine it gives us BLEACH
BLEACH is use for Household bleaches and beaching fabric
_______________________________________________
The process is named Chlor-alkali process due to the reason as below :
The process is named as Chlor-alkali process because of the product formed -Chlor for Chlorine and alkali for Sodium hydroxide

Thanks for Reading !
It's the process to obtain NaOH. It's is called Chlor -alkali because of the products formed.
Chlorine gas and NaOh
2Nacl + 2H20 ------> 2Naoh +Cl2 + H2
Electricity is passed though Nacl and H2O
