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 correct answer is: B
Explanation
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\(_2\)).
