Determination of the Ionization Constants. 
The values of the ionization constants (k and /) for either 
property of either salt were found by the method of least 
squares from the data of Tables VII and VIII for the four 
weakest solutions, for the specific gravity and surface tension 
respectively. The values thus found were employed in ecalecu- 
lating the values of the properties of the various mixtures. 
Results of the Calculations on Simple Solutions. 
Tables VII and VIII contain the results of the caleulations 
from the above formula for the two properties. 
The concentrations are expressed as in the tables above.
