Describe the electrode products using intert electrodes in concentrated aqueous sodium chlorine
Accepted Answer
In a concentrated aqueous solution of sodium chloride (NaCl), electrolysis using inert electrodes like platinum or graphite results in the following products:
At the anode (positive electrode): Chlorine gas (Cl₂) is produced due to the oxidation of chloride ions.
At the cathode (negative electrode): Hydrogen gas (H₂) is produced due to the reduction of water molecules.
The overall reaction can be summarized as:
2NaCl(aq) + 2H₂O(l) → Cl₂(g) + H₂(g) + 2NaOH(aq)
