In this video, we will discuss why it is experimentally challenging to find out the limiting molar conductivity for weak electrolytes. We will learn about Kohlrausch's law and how it can be used for weak electrolytes.Kohlrausch law and its applications are very important in the study of dilute solutions and also in the study of electrochemical cells. This law is mainly used to find the limiting .If a salt is dissolved in water, the conductivity of the (dilute) solution is the sum of two values – one depending on the positive ions and the other on the negative ions. The . Kohlrausch’s law is used to calculate the degree of dissociation of weak electrolytes ( α). The molar conductivity of the electrolyte at any concentration, C ( π 0 .

From 1875 to 1879 Kohlrausch performed numerous experiments with aqueous solutions of different salts, acids, and other electrolytes. His experiments .

In 1874, Kohlrausch formulated the law of independent migration of ions based on the experimental data of conductivities of various electrolytes. This law can be stated as .Verified by Toppr. Kohlrausch's law : The value of molar conductance at infinite dilution is give by the sum of the contributions of ions (Cation and anion) λ∞ m =xλ∞ +a +yλ∞ −e. λ+2 and λ−e ionic conductance of cation and anion x and y = no. of ions. Two applications.
