Question

According to Kohlrausch’s law, conductivity of ions is constant at

• A. fixed temperature
• B. infinite dilution
• C. 1 M concentration
• D. all the concentrations

Answer 1

The correct option is B infinite dilution

Kohlrausch's law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations. If a salt is dissolved in water, the conductivity of the solution is the sum of the conductances of the anions and cations.
