Which one of the following statements regarding electrolytic solution is not correct?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → conductivity does not depend upon solvation of ions present in solution.
The conductivity of an electrolytic solution depends on how freely ions can move in the solution.
-
Conductivity depends upon the size of ions – Correct. Smaller ions generally move faster and conduct better.
-
Conductivity does not depend upon solvation of ions – Incorrect statement. Solvation affects the effective size and mobility of ions. Highly solvated ions move more slowly, so conductivity does depend on solvation.
-
Conductivity depends upon viscosity of solution – Correct. Higher viscosity means more resistance to ion movement, so conductivity decreases.
-
Conductivity depends on temperature – Correct. Increase in temperature usually increases ion mobility and conductivity.
