334 CONDUCTIVITY OF AQUEOUS SOLUTIONS. McKAY. 



four weakest all positive, the differences exhibit the alternation 

 of sign which we would expect if they were due to accidental 

 errors. 



The results of the experiments, therefore, lead the writer to 

 conclude that it is possible, by means of the dissociation theory, 

 to calculate the conductivity of mixtures of solutions of the 

 chlorides of sodium and barium at least for solutions whose 

 concentrations are not above 2 gramme-equivalents per litre.
