AIIMS 2019 Chemistry Faraday's Laws of Electrolysis Assertion Reason Question
Assertion: One mole of silver deposits by 1 Faraday charge. Reason: Faraday charge required depends upon no of electron.
If both assertion and reason are true and reason is the correct explanation of assertion.
If 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
One mole of silver (Ag) deposits when a charge of 1 Faraday (approximately 96500 coulombs) is supplied, as silver ions (Ag⁺) each require one electron (e⁻) for reduction, aligning with the assertion. The reason is also true because the charge required for electrolysis indeed depends on the number of electrons involved in the reduction of ions, making it a correct explanation of the assertion. Options B, C, and D are incorrect because they either misinterpret the relationship between the assertion and reason or incorrectly state their validity.
