Electrolysis of brine is known by which name?
Answer and explanation
Correct answer: Chlor-alkali process
Brine is a concentrated aqueous solution of sodium chloride. During electrolysis, chlorine is produced at the anode, hydrogen at the cathode, and sodium hydroxide remains in the solution. Because the process produces chlorine and an alkali, sodium hydroxide, it is called the chlor-alkali process. Neutralisation, evaporation, and filtration are different processes, so option B is correct.
