Question 5

Limiting molar conductivity

Answer 5

Molar conductivity at infinite dilution

Question 6

Kohlrausch’s law of independent migration of ions

Answer 6

Limiting molar conductivity for any electrolyte can be expressed as the sun of independent contributions from the constituent cations and anions present
