_______Law of independent migration of ions states that limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the anion and cation of the electrolyte.

Kohlrausch

The correct answer is option 3. Kohlrausch.

The law of independent migration of ions that states that the limiting molar conductivity of an electrolyte can be represented as the sum of the individual contributions of the anion and cation of the electrolyte is known as Kohlrausch's Law.

Kohlrausch's Law is a fundamental principle in electrochemistry named after the German physicist Friedrich Kohlrausch. It states that the molar conductivity (\( \Lambda_m \)) of an electrolyte at infinite dilution can be expressed as the sum of the individual molar conductivities (\( \Lambda_m^\circ \)) of the ions present in the electrolyte. Mathematically, it can be written as:

\[ \Lambda_m = \Lambda_m^\circ(\text{cation}) + \Lambda_m^\circ(\text{anion}) \]

This law is essential for understanding the conductance of electrolytic solutions and is widely used in the study of electrolytes and their behavior in solution.
