The chlor-alkali process is done by electrolysis of what?
Answer and explanation
Correct answer: Brine
The chlor-alkali process is the electrolysis of brine, which is a concentrated aqueous solution of sodium chloride. At the electrodes, chloride ions are oxidised to chlorine at the anode, water produces hydrogen at the cathode, and sodium hydroxide remains in solution. Sugar solution, lime water, and vinegar are not the industrial feedstock for this process. Hence, option A is correct.
