Conductivity , Molar conductivity and Equivalent Conductivity

Question

Statement 1: For measuring resistance of an ionic solution, an AC source is used.
Statement 2: Concentration of ionic solution will change if DC source is used.

Moderate

A

Both statements 1 and 2 are correct
B

Both statements 1 and 2 are incorrect
C

Statement 1 is correct statement 2 is incorrect
D

Statement 1 is incorrect statement 2 is correct

Solution

Concentration of ionic solution changes on using DC current as a source of energy while on passing AC current concentration does not change. Hence, AC source is used for measuring resistance.
