Used in the chloralkali industry. This industry produces chlorine and sodium hydroxide from brine otherwise known as saturated aqueous solutions containing NaCl.
Chlorine
Sodium Hydroxide
Oxidation Reaction
2Cl−(aq)→Cl2(g) + 2e−
Reduction Reaction
2H2O(ℓ) + 2e−→H2(g) + 2OH−
Remaining Na+ reacts with OH- to make NaOH
Na+(aq) + OH−(aq)→NaOH(aq)
Overall
2NaCl(aq)+2H2O(ℓ) → Cl2(g)+H2(g)+2NaOH(g)
