Question

Exlain what would happen if electricity is passed through aqueous solution of brine

Answer 1

Explanation:

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
