Which of the following is correct regarding the variation of conductivity with dilution ?

Options

A. It decreases for strong electrolytic but increases weak electroyltes
B. It decreases for both strong and weak electrolytes
C. It increases for both strong electrolytes and weak electrolnytes
D. It increases for strong electrolytes but decreases weak electrolytes

Answer

B

Explanation

Conductivity always decreases with decreases in con-centration for weak as well as strong electrolytes. This can be explanied by the fact that the number ions per unit volume that carry the current in a solution decreases on dilution
