NEET Chemistry (general) Assertion Reason Question
Assertion (A): The standard electrode potential of a half-cell can be determined by measuring the emf of a cell where the standard hydrogen electrode is used as the anode. | Reason (R): The standard electrode potential of the standard hydrogen electrode is zero.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true but (R) is false.
(A) is false.
Correct Answer
Detailed Explanation
The assertion is correct because the standard electrode potential of a half-cell can be determined by using the standard hydrogen electrode with known zero potential as a reference. The reason correctly explains this because it states the zero potential of the standard hydrogen electrode.
