Kohlrausch 's Law of Independent Migration of Ions can be represented graphically by plotting an electrolyte's molar conductivity (λm) against the square root of its concentration (√c). According to Kohlrausch 's Law , the plot should be a straight line with an intercept equal to the limiting molar conductivity (λ∞m) and a slope similar to -A, where A is a constant. The value of A depends on the type of electrolyte and the temperature at which the measurement is taken. The graph obtained ... Kohlrausch law states that the equivalent conductance of an electrolyte at infinite dilution is equal to the sum of the individual conductance of anions and cations. Learn how to calculate the limiting molar conductivity, dissociation constant, solubility constant and cell potential using this law with examples and FAQs. Kohlrausch ’s law Aug 26, 2022, 16:45 IST About Kohlrausch law EFFECT OF DILUTION ON CONDUCTANCE (i) When we increase the dilution of electrolyte, magnitude of specific conductance decreases, because number of ions in 1 cm3 volume of electrolyte decreases. (ii) When dilution of electrolyte increases, magnitude of molar conductance and equivalent conductance increases, because number of ions increases after dilution. (iii)The molar conductivity of strong electrolytes is found to vary with ... Why does Kohlrausch ’s law is referred as independent migration of ions law ? Answer: Kohlrausch 's law of independent migration asserts that in the limit of infinite dilution, each ionic species contributes to the conductivity of the solution that is solely reliant on the nature of that particular ion and independent of the other ions present. Q 2.
