Question

What is chlor-alkali process?Write a balanced chemical equation for the reaction involved in this process, to justify your answer. ​

Answer 1

Answer:

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.

Answer 2

Answer:

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.

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.
