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

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.
