Question

State Kohlrausch's law of independent migration of ions. Why does the conductivity of a solution decrease with dilution?

Answer

Kohlrausch's law of independent migration of ions: It states that the limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of its anion and cation.
straight lambda subscript infinity space equals space straight lambda subscript straight a space plus straight lambda subscript straight c
where space straight lambda subscript straight a space and space straight lambda subscript straight c space are space anion space and space cation
A conductivity of a solution decreases with dilution because it leads to decrease in a number of ions per unit volume.
