Brine is highly concentrated water solutions of sodium chloride
When electricity is passed through brine , it decomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode. Sodium hydroxide solution is also formed near the cathode.
2NaCl(aq)+2H2O(l)→2NaOH(aq)+CCl(g)+H2(g)
