  • question_answer 40)
      Which of the statements about solutions of electrolytes is not correct? (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

    Answer:

                      (c) 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 solvent 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.
