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.
