What is chlor-alkali process?Write a balanced chemical equation for the reaction involved in this process, to justify your answer.
Answers
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. 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.
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. 35 million tons of chlorine were prepared by this process in 1987.
