The values of the specific molecular conductivity at infinite 
dilution for potassium chloride, sodium chloride, and hydrochlorie 
acid respectively, were taken to be 1220 x 10-8, 1030 x 10-8 and 
3500 x 10~-§ according to Kohlrausch’s determination.* 
Results of Observations on Mixtures. 
(A).—Sodium and Potassium Chlorides. 
The following series of mixtures of potassium and sodium 
chloride solutions were examined :
