What is the equation of chlor-alkali industry?

The chemical equation of chlor-alkali industry is 2NaCl+2H2O=2NaOH+Cl2+H2.

Chlor-alkali industry refers to the industrial production of sodium hydroxide (NaOH), chlorine gas (Cl2) and hydrogen gas (H2) by electrolysis of saturated sodium chloride solution, from which a series of chemical products are produced, which is called chlor-alkali industry.

Chlor-alkali industry is one of the most basic chemical industries, and its products are widely used in light industry, textile, metallurgy, petrochemical industry and public utilities. There are three main processes: diaphragm method, double electrolytic cell method and mercury electrolytic cell method.

reaction principle

Anode reaction: 2cl-2e-= Cl2 = (oxidation reaction).

H+ can get electrons more easily than Na+, so the electrons that H+ keeps getting from the cathode are reduced to hydrogen atoms, which are combined into hydrogen molecules and released from the cathode.

Cathode reaction: 2H++2e-=H2↑ (reduction reaction).
