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
Correct answer is B
During the electrolysis of aqueous sodium chloride using inert electrodes (such as platinum or carbon), the cations (H\(^+\)) are attracted to the cathode and are reduced to form hydrogen gas (H\(_2\)). The anions (OH\(^-\)) are attracted to the anode and are oxidized to form oxygen gas (O\(_2\)).
