Assertion (A): DC can not be used during measurement of resistance of an ionic solution.

Reason (R): DC changes the composition of solution and solution cannot be connected to the bridge like metallic wire.

View answer and explanation

Correct option: A

Assertion and Reason both are correct and Reason is the correct explanation of Assertion.

Option A (Assertion and Reason both are correct and Reason is the correct explanation of Assertion) is correct because DC electrolysis changes the ionic solution's composition, and the solution's resistance can't be measured using a Wheatstone bridge with DC.
