Question
Which of the statements about solutions of electrolytes is not correct?
Options
Conductivity of solution depends upon size of ions.
Conductivity depends upon viscosiy of solution.
Conductivity does not depend upon solvation of ions present in solution.
Conductivity of solution increases with temperature.
Solution
Conductivity does not depend upon solvation of ions present in solution.
Explanation:
Conductivity depends upon salvation of ions present in the solution. The greater the salvation of ions, the lesser is the conductivity.

The following questions are case-based questions. Read the passage carefully and answer the questions that follow:
| Rahul set up an experiment to find the resistance of aqueous KCl solution for different concentrations at 298 K using a conductivity cell connected to a Wheatstone bridge. He fed the Wheatstone bridge with a.c. power in the audio frequency range 550 to 5000 cycles per second. Once the resistance was calculated from the null point, he also calculated the conductivity K and molar conductivity ∧m and recorded his readings in tabular form. |
