Hi there,

Hope you are doing good.

Chlor-alkali process is used to prepare sodium hydroxide using sodium chloride.

When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide.

2NaCl (aq) + 2H₂O (l) à 2NaOH (aq) +  Cl₂ (g) + H₂ (g)

Thanks and Regards
