What is the law of Kohlrausch?
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.
What is Kohlrausch law and its applications?
Kohlrausch Law relates to the limiting molar conductivity of an electrolyte to its constituent ions. It basically states that the limiting molar conductivity of an electrolyte is equal to the sum of individual limiting molar conductivities of the cations and anions which make up the electrolyte.
What is Kohlrausch law 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 write its equation?
Λm∘=vcΛm∘+vaΛa∘ where vc and va are the number of cations and anions respectively in one formula unit of the compound.
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.
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.
What is kohlrausch law class 12?
What is Kohlrausch’s Law? 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.
What is kohlrausch law Wikipedia?
Kohlrausch’s law of independent migration of ions Friedrich Kohlrausch in 1875–1879 established that to a high accuracy in dilute solutions, molar conductivity can be decomposed into contributions of the individual ions. This is known as Kohlrausch’s law of independent ionic migration.
What is kohlrausch law of independent migration of ions Class 12?
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 Shaalaa?
Solution. Kohlrausch Law: 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.
Who invented kohlrausch law?
Friedrich Wilhelm Georg Kohlrausch (Figure 1) was a German physicist who studied the electrical conductivity of electrolyte solutions and greatly contributed to the understanding of their electrical features, particularly important for electrochemistry and dissociation theory.
What is kohlrausch law of independent migration of ions write two applications?
Kohlrausch law states that, “at infinite dilution, each ion migrates independently of its co-ion and makes its own contribution to the total molar conductivity of an electrolyte irrespective of the nature of other ion with which it is associated.”
