Question

For the measurement of conductance of an electrolytic solution,
which of the following is correct?

Direct current cannot be used as it changes the composition of solution

Alternating current cannot be used as it changes the
composition of the solution.

Both Alternating current as well as Direct current can be used as they do not change the composition of the solution

Either Alternating or Direct current can be used as both change the composition of
solution​

Answer 1

Answer:

DC cannot be used as it changes the composition of solution

Explanation

AC can be used  to solve this problem.

Answer 2

For the measurement of conductance of an electrolytic solution, the following statement is correct:

Direct current cannot be used as it changes the composition of the solution.

- If we use Direct current for the measurement of the conductance of an electrolytic solution, then it causes the polarization of electrodes and the electrolyte.

- It leads to a change in composition and hence an error is observed in the measurement of the conductance.

- While in the case of the Alternating Current, it does not cause any polarization.

- Therefore, Direct Current is not used in measuring electrolytic conductance as it changes the composition of the solution.
