Electrolysis of brine is known by which process name?
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 the solution. Because the process yields chlorine and an alkali, sodium hydroxide, it is called the chlor-alkali process. Neutralisation, evaporation and filtration are different processes.
