What is the process of electrolysis of brine called?
Answer and explanation
Correct answer: Chlor-alkali process
Brine is a concentrated aqueous solution of sodium chloride. During electrolysis, chloride ions produce chlorine at the anode, water produces hydrogen at the cathode, and sodium hydroxide remains in solution. Because the products include chlorine and an alkali, this industrial method is called the chlor-alkali process. Therefore option B is correct; acidification, simple water decomposition, and crystallisation do not describe this complete electrolytic process.
