Question

How do you determine equivalent conductance of strong electrolyte at infinite dilution ?

Answer 1

The equivalent conductivity of a strong electrolyte at infinite dilution is equal to the sum of the equivalent conductivities of the anions and cations.

Answer 2

The equivalent conductance of S.E (strong electrolyte) is determined by Kohlrausch’s law at infinite dilution.

Explanation:

• When the dilution increases and reaches infinity (i.e., infinite dilution), the electrolytes dissociates completelyinto ions, and the degree of dissociation beomes unity.
• For strong electrolytes, at infinite dilution the equivalent conductance is determined by Kohlrauch's law.
• It states that at ∞ dilution, the equivalent conductance is equal to the sum of individual eq. conductance of the anions and cations.
