Variation of ConductivityElectrochemistry

Why can't the Limiting Molar Conductivity (Λm\Lambda^\circ_m) of a weak electrolyte be determined by extrapolation of the Λm\Lambda_m vs c\sqrt{c} graph?.

Expert Answer

Because the curve becomes very steep at low concentrations (infinite dilution) and does not intersect the y-axis linearly.
