Question

Write the relation between molar conductivity and molar ionic conductivities for the electrolytes:

1. Na₂SO₄
2. AlCl₃

Answer 1

If Λ₀ is molar conductivity of an electrolyte at infinite dilution and `λ_+^0 and λ_-^0` are molar ionic conductivities then,

1. \[\ce{Λ_{0Na_2SO_4} = 2λ^0_{Na^+} + λ^0_{SO_4^{2+}}}\]
2. \[\ce{Λ_{0AlCl_3} = λ^0_{Al_{3+}} + 3 λ^0_{{Cl}^-}}\]
