Give the process of manufacture of NaOH using Castner-kellner cell

1.	Give the process of manufacture of NaOH using Castner-kellner cell
Answer» Caustic Soda • electrolysis of aq. NaCl NaCl + H2O NaCl — Na(+) + Cl(-) H2O — H(+) + OH(-) At CATHODE 2H(+) + 2é - H2AT anode 2CL(-) — Cl2 + 2éButCl2 + NaOH — [Hot] — NaCl + NaClO3 + H2O [COLD] — NaCl + NaClO + H2OSo to resolve this problem Castner kellner cell is USED, in which, Hg cathode ( Na> H) At cathode Na(+) + é — Na— Na-Hg ( Sodium amalgam) At anode 2Cl(-) — Cl2 + 2é
