On electrolysis of aqueous $N a C l$ , Hydrogen gas is produced at which electrode?

Open in App

Solution

Electrolysis of the ionic compound Sodium chloride( $N a C l$ ) in the aqueous form produces Hydrogen gas and Chlorine gas.
The Chlorine gas is produced at the electrode Anode.
And the Hydrogen gas is produced at the electrode Cathode.
The anodic and cathodic reaction is,
Cathode: $H_{2} O (l) + 2 e^{-} \to \underset{H y d r o g e n g a s}{H_{2} (g)} + 2 O H^{-}$
Anode: $2 C l^{-} \to \underset{C h l o r i n e g a s}{C l_{2} (g)} + 1 e^{-}$
So the Hydrogen gas is produced in the Cathode electrode.
