Conductivity , Molar conductivity and Equivalent Conductivity

Question

Which of the following statements about solution of electrolytes is not correct?

Moderate

A

Conductivity of solution depends upon size of ions
B

Conductivity depends upon viscosity of solution
C

Conductivity does not depend upon solvation of ions present in solution
D

Conductivity of solution increases with temperature

Solution

Solution consists of electrolytes is known as electrolytic solution and conductivity of electrolytic solution depends upon the following factors.
(i) Size of ions: As ion size increases, ion mobility decreases and conductivity decreases.
(ii) Viscosity of solution: Greater the viscosity of the solution, lesser will be the conductivity of the solution.
(iii) Solvation of ions: Greater the solvation of ions of an electrolyte, lesser will be the electrical conductivity of the solution.
(iv) Temperature of medium : Conductivity of solution increases with increase in temperature.
