### Definitions: - Molar Conductivity (Λm): The conductivity of an electrolyte solution divided by its molar concentration. It is given by: \[ \Lambda_m = \frac{\kappa}{c} \] where \( \kappa \) is the conductivity and \( c \) is the concentration. - Limiting Molar Conductivity (\(\Lambda_m^\circ\)): The molar conductivity at infinite dilution, where ion-ion interactions ________ ________ _________ ___ ____ _________.
