What is chlor -alkali process write down its equation.?

The chlor-alkali process is an industrial method for producing chlorine, sodium hydroxide (caustic soda), and hydrogen gas from brine (sodium chloride solution). The key chemical reactions involved are:

1. Chlorine gas is produced at the anode: 2Cl⁻ → Cl2 + 2e⁻
2. Hydrogen gas is produced at the cathode: 2H2O + 2e⁻ → 2OH⁻ + H2
3. Sodium hydroxide is also produced: 2Na⁺ + 2OH⁻ → 2NaOH
