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.
