When an electric current is passed throughconcentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms. ... However, sodium is too reactive for this to happen so hydrogen is given off instead.

Answer -:
when electric current passed through brine, hydrogen gas is evolved at the anode, chlorine gas is evolved at the cathode, and sodium hydroxide is formed in the electrolysing solution.
Sodium chloride + water → sodium hydroxide + chlorine + Hydrogen
2NaCl(aq) + 2H2O(l) → 2NaOH(aq) + Cl2 (g) + H2(g)
These three co-products are all very useful chemicals.
