What are the main products obtained in the chlor-alkali process?
Answer and explanation
Correct answer: Chlorine, hydrogen and sodium hydroxide
In the chlor-alkali process, aqueous sodium chloride (brine) is electrolysed. Chloride ions are discharged at the anode to form chlorine gas, water is reduced at the cathode to form hydrogen gas, and sodium hydroxide remains in the solution. Thus the three main products are chlorine, hydrogen, and sodium hydroxide. The other combinations belong to unrelated reactions.
