Which aqueous solution is electrolysed in the chlor-alkali process?
Answer and explanation
Correct answer: Aqueous sodium chloride solution (brine)
In the chlor-alkali process, concentrated aqueous sodium chloride solution, called brine, is electrolysed. It produces chlorine gas, hydrogen gas, and sodium hydroxide. An aqueous calcium hydroxide solution is lime water; it is not the reactant used in the chlor-alkali process.
