Answer» (i) Sodium hydrogen carbonate is an essential ingredient in most antacids because it is slightly alkaline in nature. (ii) When sodium chloride is electrolysed, sodium is obtained at cathode which then reacts with water to give alkali and hydrogen. Thus alkali is the main product. On the other hand, chlorine is obtained at anode. So it is called chlor-alkali process.
