Calculate the molar conductivity at infinite dilution of acetic acid from the following data:
Λ∞m (HCl) = 426 ohm–1 cm2 mol–1, Λ∞m CH3COONa = 91 ohm–1 cm2 mol–1 and Λ∞m(NaCl) = 126 ohm–1 cm2 mol–1.
Acetic acid is weak electrolyte than HCl and NaCl which is strong electrolyte.
Acoording to kohlransch's law
Ans. 391 ohm–1 cm2 mol-1
