In 1892, the electrolysis of brine was discovered as a method for making both sodium hydroxide and chlorine, and since the 1960s it has boon the only method of manufacture of sodium hydroxide.       2NaCl + 2H2O → 2NaOH + H2 + Cl2The brine that is used for the electrolysis must be purified, and calcium, magnesium, and sulfate ions are removed by precipitation reactions.     Na2CO3 + CaCl2 → CaCO3 + 2NaCl     2NaOH + MgCl2 → Mg(OH)2 + 2NaCl     BaCl2 + Na2SO4 → BaSO4 + 2NaClIf sodium hydroxide built up near the anode it would react with chlorine to give sodium hypochlorite as a side product.     Cl2 + 2NaOH → NaOCl + NaCl + H2OThe mercury cell has no diaphragm but is made of two separate compartments. The sodium amalgam enters a separate denuding chamber where the sodium metal reacts with water. Thus, the overall reaction is identical to that or the diaphragm cell.

 Sodium hydroxide (CAS NO.1310-73-2), also called  lye and caustic soda, is a caustic metallic base when dissolved in a solvent such as water. It forms a strong alkaline solution, however, only the hydroxide ion is basic. It should be stored in an airtight container, because it is hygroscopic and readily absorbs carbon dioxide from the air.
