The products formed at cathode and anode by electrolysis of aqueous NaCl solution respectively are
The products formed at cathode and anode by electrolysis of aqueous NaCl solution respectively are
Na, Cl2
Na, O2
H2, Cl2
H2, O2
The Correct Option is C
Solution and Explanation
The electrolysis of aqueous NaCl (sodium chloride) solution results in the following products at the cathode and anode:
Cathode: H2 (hydrogen gas) is produced. Anode: Cl2 (chlorine gas) is produced.
Therefore, the correct answer is H2, Cl2.

Concepts Used:
Electrolysis
Electrolysis:
Electrolysis is the process by which an element is decomposed and undergoes some chemical change under the influence of any electric current. The first-ever electrolysis was executed out by Sir Humphrey Davey in the year 1808. Electrolysis can occur in both Galvanic cells and Electrolytic cells.
Applications of Electrolysis:
- Electrolytic cells are used for the production of Hydrogen and Oxygen gas from water.
- They are used for the large-scale production of pure metals like sodium, copper, magnesium, etc.
- They are used to extract Aluminium from Bauxite.
- Electrolytic cells are used for electroplating, a process by which a thin protective layer of one metal is formed over another metal, mostly for protection.
- Electrolysis is used for the electrorefining of non-ferrous metals.
