What is kohlrausch law of independent migration of ions?
Kohlrausch’s law of independent migration of ions states that the limiting molar conductivity of an electrolyte can be represented as the sum individual contributions of its cations & anions. The conductivity of a solution decrease with dilution because less ions are present for conduction.

What is kohlrausch law of independent migration of ions and what are its applications?
Kohlrausch law of independent migration of ions: The law states that at infinite dilution, each ion migrates independently of its co-ion and make its own contribution to the total molar conductivity of an electrolyte irrespective of the nature of other ion with which it is associated.
What is Kohlrausch’s law explain its any two applications of kohlrausch law?
Kohlrausch Law refers to an electrolyte’s limiting molar conductivity to its constituent ions. It indicates that an electrolyte’s limiting molar conductivity is equal to the sum of the individual limiting molar conductivities of the cations and anions that make up the electrolyte.
Is kohlrausch law or kohlrausch law of independent migration of ions is same?
Complete answer: Kohlrausch’s law of independent migration of ions states that equivalent conductivity of an electrolyte is equal to the sum of conductance of anions and cations at infinite dilution.
What is kohlrausch law explain with example?
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.
What is kohlrausch law?
Definition of Kohlrausch’s law : a statement in physical chemistry: the migration of an ion at infinite dilution is dependent on the nature of the solvent and on the potential gradient but not on the other ions present.
Who discovered kohlrausch law?
Friedrich Kohlrausch
Question: 1. Who discovered the law of the independent migration of ions? Answer: A study of the conductivities of different electrolytes by Friedrich Kohlrausch led to the discovery of this law.
How is kohlrausch law calculated?
Kohlrausch law
- α = Λ/ Ëm∘
- α = dissociation constant.
- Λ = molar conductivity of ion.
- Ëm° = limiting molar conductivity of ion.
What is kohlrausch law statement?
What is kohlrausch law Shaalaa com?
The equivalent conductivity of an electrolyte at infinite dilution is the sum of two values on depending upon the cation and the other upon the anion.
