Limiting molar ionic conductivities of uni-univalent electrolyte are 5...
Given:

Limiting molar ionic conductivities of uni-univalent electrolyte (Λ±) = 57 and 73 S cm2 mol-1


To find:

Limiting molar conductivity of the solution (Λ0)


Explanation:

The molar conductivity of an electrolytic solution is the conductance of all the ions produced by one mole of the electrolyte when dissolved in a specified volume of the solution.


Definition:

The molar conductivity of an electrolytic solution at infinite dilution is called the limiting molar conductivity (Λ0).


Kohlrausch's Law:

According to Kohlrausch's Law, the limiting molar conductivity of an electrolyte can be calculated as the sum of the limiting molar ionic conductivities of the cations (Λcation) and anions (Λanion).

Λ0 = Λcation + Λanion


Calculation:

Given that the limiting molar ionic conductivities of the cation and anion are 57 and 73 S cm2 mol-1 respectively.

Λ0 = 57 + 73 = 130 S cm2 mol-1


Answer:

The limiting molar conductivity of the solution is 130 S cm2 mol-1 (Option A).
