TABLE IV. 



Determination, of lonization Coefficients in the Mixtures. 



The method of determining the coefficients of ionization of 

 the two electrolytes in a mixture has been fully described by 

 l Prof. MacGregor. Curves are drawn showing the relation of 

 the dilution to the concentration of ions for simple solutions of 

 each salt. From these curves the concentration of ions and the 

 dilution in the regions of the mixture occupied by the respective 

 electrolytes are found by a graphical process, and the products 

 of these quantities give the ionization coefficients. 



Results of Observation* and Calculations of Conductivity of 



Mixtures. 



Table V gives the necessary data for the calculation of the 

 conductivity of the mixtures examined, and the results obtained. 

 The concentrations of the constituent solutions are expressed in 

 terms of gramme-equivalent-i per litre at 18 0. The regional 

 dilutions are in litres per gramme-equivalent at 18 C. The 

 specih'c conductivities are expressed as in Table I. The differ- 

 ences between the calculated and observed values of the 

 conductivity are given as percentages of the observed value.
