Vedclass · Answer

(C) In the $Castner-Kellner$ process,a brine solution ($NaCl$ aqueous) is electrolyzed using a mercury cathode and a carbon anode.At the mercury cathode,sodium ions $(Na^+)$ are reduced to form sodium metal,which then dissolves in the mercury to form sodium amalgam ($Na-Hg$ alloy).This sodium amalgam is subsequently reacted with water to produce sodium hydroxide $(NaOH)$,hydrogen gas,and mercury.

In the $Castner-Kellner$ cell for the production of sodium hydroxide,which of the following occurs?
