Name the 3 products of the chlor-alkali process.
State two uses of each product

Answer this

Dear student,

Chlor- alkali process is a type of decomposition reaction.
When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide. The process is called the chlor-alkali process because of the products formed- chlor for chlorine and alkali for sodium hydroxide. Following is the chemical equation for the process

 2NaCl (aq) + 2H2O (l) → 2NaOH (aq) + Cl2 (g) + H2 (g) 

Chlorine gas is liberated at the anode while hydrogen gas is liberated at the cathode.

Three products of this process are- 
1) Sodium hydroxide (NaOH)
2) Chlorine gas (Cl2)
3) Hydrogen gas (H2)

Uses are as follows-
1) Sodium hydroxide (NaOH)
- Used to make soap.
- Used in drain cleaners

2) Chlorine gas (Cl2)
- Used as a disinfectant
- Used in the manufacture of dyes and plastics.

3) Hydrogen gas (H2)
- Used in the synthesis of ammonia
- Used as rocket fuel.

The three products are : Sodium hydroxide (NaOH), Chlorine (CL2) Hydrogen (H2)
 - NaOH - for soaps and detergents and paper making or artificial fibres.
 -Cl2 - PVC, pesticides, CFCs
  -H2 - fuels, margarine, NH3 for fertilizers.

Three products formed by the chlor alkali process are H2, Cl2 and NaOH. Uses of these products are as follows :-
Uses of H2
1. Hydrogenation of oil to get vegetable ghee (margarine)
2. To make ammonia for fertilizers.
Uses of Cl2
1. To make plastic, e.g. PVC
2. To make CFCs, chloroform, dyes etc.
Uses of NaOH
1. Used in making soap and detergent.
2. Used in manufacturing of paper
