Question

Why is process of electrolysis of brine solution called chlor - alkali process? Name the byproduct formed during this process

Answer 1

Explanation:

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 fertilizers.
• 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.
• H2+ Cl2 --> 2HCl
• Hydrochloric acid is used 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.

By products formed in Chlor-alkali process:

The three byproduct formed in this process i.e.

1. Sodium hydroxide.
2. Sodium hydroxide.Hydrogen gas
3. Sodium hydroxide.Hydrogen gasChlorine gas

Answer 2

Answer: it is because of the products formed

Explanation: chor from chorine and alkali for sodium hydroxide
