Arrhenius Arrhenius The resistance of an electrolyte is increased when the dilution is doubled In very dilute solutions the conductivity is nearly proportional to the concentration The conductivity of a solution is equal to the sum of conductivities of the salt and the solvent If these laws are not observed, it must be due to a chemical reaction between the substances including the solvent The electrical resistance rises with increasing viscosity, complexity of the ion, and the molecular mass of[.]
