what is chlor alkali process write its chemical equation which gas is evolved at cathode and anode
Answers
Answer:
The chloralkali process is an industrial process for the electrolysis of sodium chloride solutions. It is the technology used to produce chlorine and sodium hydroxide,which are commodity chemicals required by industry.
2Cl− → Cl2 + 2e−
2NaOH (aq) + Cl2 (g) + H2 (g) Chlorine gas is liberated at the anode while hydrogen gas is liberated at the cathode.

Heya Mayank...!!!
Hope you are doing gr8...
Here is your answer mate...!
Explanation:
It 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.
