Kohlrausch’s Law
1. Define Kohlrausch Law
Kohlrausch law, named after Friedrich Kohlrausch, describes the conductivity of electrolyte solutions and states that each ion in a solution contributes independently to the overall conductivity.
2. What is Mathematical Expression of Kohlrausch Law?
The mathematical expression of Kohlrausch Law is:
Λm = λ+c+ + λ−c−
3. What is Infinite Dilution in Electrochemistry?
Infinite dilution refers to the state when the concentration of an electrolyte becomes extremely low, approaching zero. In this condition, ions are widely separated, allowing for precise measurement of ion conductivities.
4. What is Kohlrausch Law and its Applications?
Kohlrausch’s law helps predict and understand the conductivity of electrolyte solutions. Its applications include determining molar conductivities and ion mobility and studying the dissociation of electrolytes in various concentrations.
5. Who Discovered Law of Independent Migration of Ions?
The law of independent migration of ions was discovered by Friedrich Kohlrausch in the late 19th century, contributing significantly to our understanding of electrolyte behavior.
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.
