Aqueous sodium chloride solution is the starting material for which industrial process?
Answer and explanation
Correct answer: Chlor-alkali process
An aqueous solution of sodium chloride is called brine. In the chlor-alkali process, brine undergoes electrolysis. Chlorine is released at the anode, hydrogen at the cathode, and sodium hydroxide remains in the solution, subject to industrial separation and operating conditions. Therefore option B is correct. The other choices are not the name of the industrial electrolysis process that begins with brine.
