On the electrolysis of HCl, hydrogen gets liberated at -

Answer:

Solution:

In the electrolysis of HCl, the ions present are H⁺ and Cl⁻.

At the cathode, reduction takes place:

$2 H^{+} + 2 e^{-} \to H_{2}$

Hydrogen ions gain electrons, and hydrogen gas is liberated at the cathode.

At the anode, chloride ions undergo oxidation:

$2 C l^{-} \to C l_{2} + 2 e^{-}$

Therefore, hydrogen is liberated at:

(B) Cathode
