Chemistry Question on Electrolysis
The products formed at cathode and anode by electrolysis of aqueous NaCl solution respectively are
A
Na, Cl2
B
Na, O2
C
H2, Cl2
D
H2, O2
Answer
H2, Cl2
Explanation
Solution
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.
