Electrolysis of an aqueous solution of sodium _________ produces hydrogen at cathode and chlorine at anode. (Chloride/hydroxide)

Open in App

Solution

Electrolysis is the process of splitting electrolytes in the presence of an electric current. It involves two electrodes, a cathode, and an anode. An electrolyte solution is placed in between the two electrodes.
The reaction for the electrolysis of aqueous Sodium chloride is shown below.
$2 NaCl (aq) + 2 H_{2} O (l) ⇌ 2 NaOH (aq) + H_{2} (g) + {Cl}_{2} (g) (Sodium (Water) (Sodium (Hydrogen) (Chlorine) chloride) hydroxide)$
In this process, hydrogen is produced at the cathode and Chlorine at the anode.
Thus, electrolysis of an aqueous solution of Sodium chloride produces hydrogen at the cathode and chlorine at the anode.
