Question

Which of the following statements is correct regarding the conductivity of solutions of electrolytes?

(a) It is independent of the size of the ions

(b) It is independent of the viscosity of the solution

(c) It depends on the solvation of ions present in solution

(d) It decreases with temperature

This question was posed to me during an interview.

I would like to ask this question from Conductance of Electrolytic Solutions topic in division Electrochemistry of Chemistry – Class 12

Answer 1

The correct option is (c) It depends on the solvation of ions present in solution

To elaborate: Conductivity of a solution is inversely proportional to the size of the ions present in it, the viscosity of the solution and the solvation of the ions in the solution. Conductivity increases with temperature as it can cause an increase in the number of ions in solution.
