In Nelson cell, $N a O H$ are formed at ________(cathode/anode) electrode.

Open in App

Solution

Reaction involved-

$2 N a C l + 2 H_{2} O \to H_{2} + {C l}_{2} + 2 N a O H$

In Nelson Cell, electrolysis of concentrated sodium chloride solutions produces chlorine gas, hydrogen gas, and aqueous sodium hydroxide. Chlorine is produced at the anode. Hydrogen and sodium hydroxide both are produced at the $c a t h o d e$ .

Hence, the correct answer is Cathode.
