Question on: JAMB Chemistry - 2023
Â
What is the product of the electrolysis of aqueous sodium chloride (NaCl) using inert electrodes?
Hydrogen gas at the cathode and chlorine gas at the anode
Hydrogen gas at the cathode and oxygen gas at the anode
Sodium metal at the cathode and chlorine gas at the anode
Sodium metal at the cathode and oxygen gas at the anode
The product of the electrolysis of aqueous sodium chloride (NaCl) using inert electrodes is hydrogen gas (Hâ‚‚) at the cathode and chlorine gas (Clâ‚‚) at the anode.
The overall reaction can be represented as follows:
\[ 2 \, \text{H}_2\text{O} + 2 \, \text{NaCl} \rightarrow \text{H}_2 \uparrow + \text{Cl}_2 \uparrow + 2 \, \text{NaOH} \]
Hydrogen gas is produced at the cathode, and chlorine gas is produced at the anode.
