Question

Assertion: The electrode potential of a standard hydrogen electrode is equal to zero.

Reason: The value has been obtained on the basis of experimental observations.

Options

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If Assertion is CORRECT but Reason is INCORRECT.

Explanation:

The electrode potential of the standard hydrogen electrode (SHE) is assigned a value of zero by convention, not from experimental observations. This is done to provide a reference point for measuring the electrode potentials of other electrodes.

Assertion is correct; the electrode potential of SHE is 0 V.

Reason is incorrect; it is not based on experiments but is defined by convention.
