Solution

The correct option is D

All Of These.


The explanation for the correct option:

Option(D): All Of These.

  • Brine is particularly known as a highly concentrated solution of common salt in water i.e sodium chloride.
  • The electrolysis of brine is known as the method basically used to produce chlorine on a large scale from salt.
  • During the electrolysis of brine or NaCl produces hydrogen at the cathode and chlorine at the anode.
  • However, the electrolyte sodium hydroxide remains in the solution.
  • The chemical reaction showing the electrolysis of brine can be shown as:

2NaCl(s)(Sodiumchloride)+H2O(l)WaterelectrolysisCl2(g)Chlorine+H2(g)Hydrogen+NaOH(aq)Sodiumhydroxide

Hence, as the electrolysis of brine yields chlorine, hydrogen, and sodium hydroxide, the correct option is: All of the above(Option(D)
