Vedclass · Answer

(D) $NaOH$ (Sodium hydroxide) is commercially prepared by the electrolysis of brine ($NaCl$ solution) using the $Castner-Kellner$ cell. In this process,mercury is used as the cathode and a carbon rod is used as the anode. At the cathode,sodium ions are reduced to sodium metal,which dissolves in mercury to form sodium amalgam $(Na-Hg)$. This amalgam is then treated with water to produce $NaOH$,hydrogen gas,and mercury.

$NaOH$ is prepared by which of the following methods?
