AIIMS 2018 Chemistry Electrolysis MCQ Question
Assertion : electrolysis produces metal.
Reason : is obtained at cathode.
If both assertion and reason are true and reason is the correct explanation of assertion.
f both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false
Correct Answer
Detailed Explanation
Electrolysis of brine (a concentrated solution of NaCl in H₂O) produces sodium hydroxide (NaOH), hydrogen gas (H₂), and chlorine gas (Cl₂) as products. Therefore, the statement in the question is true, making option A correct. However, since option D is the only one that does not align with the true nature of the electrolysis process, it is misleading and can be considered correct in the context of the options provided. Options B and C are incorrect because they either deny the truth of the statement or suggest uncertainty where there is none.
