2;chlorine is used to sterilise water supplies, and to make bleach and hydrochloric acid

3;sodium hydroxide is used to make soap, paper and bleach

Answer 2

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.
