Application of Kohlrausch’s Law
Some of the critical uses of Kohlrausch’s Law include:
- Calculation of the dissociation constant of an electrolyte: Kohlrausch’s Law can be used to determine the dissociation constant of an electrolyte by studying the molar conductivity at infinite dilution.
- Calculating the limiting molar conductivity of a weak electrolyte: The law allows for estimating the limiting molar conductivity of weak electrolytes, which is essential for understanding their behavior in dilute solutions.
- Determination of the degree of dissociation of weak electrolytes: Kohlrausch’s Law can be used to determine the degree of dissociation of weak electrolytes by studying their molar conductivity at different concentrations.
- Calculation of the solubility of sparingly soluble salts: The law can be used to calculate the solubility of sparingly soluble salts by determining their limiting molar conductivity.
- Determination of the transport number of ions in an electrolyte: Kohlrausch’s Law can be used to calculate the transport number of ions in an electrolyte, which is an essential parameter in electrochemical systems.
- Determination of the ionic strength of a solution: Kohlrausch’s Law can be used to determine the ionic strength of a solution, which is a crucial parameter in electrochemical systems.

Kohlrausch Law
Kohlrausch’s law, also known as the law of Independent migration of Ions, tells us that the total of the limiting molar conductance of cations and anions of an electrolyte is equal to the molar conductivity of that electrolyte. This law helps us study electrochemical cells and diluted liquids and is applicable in determining weak electrolytes’ molar conductivity.
In this article, we will learn the concepts of Kohlrausch law, its applications, etc. We have to study Kohlrausch Law in Class 12 for board exams.
