[ARCHIBALD 1 CONDUCTIVITY OF AQUEOUS SOLUTIONS 



75 



Eesults op Observ^ations and Calculations on Mixtures. 



The table below coutains the data necessary for, and the restilts of, 

 the cak-idations of. the conductivit}^ of each mixture examined. The con- 

 centrations of ions are expressed, as in the former tables. Concentrations 

 of solutions, are expressed, in terms of equivalent gramme-molecules per 

 litre at 18° C. Conductivities are specific conductivities at 18° C. in terms 

 of 10"^ times the specific conductivity of mercury at 0° C. The column 

 headed : Volumes, gives the volumes (in cubic centimetres) of KCl and 

 NaCl solutions mixed with 25 c.c. each, of the K.^ 80^ and Na^ SO^ solu- 

 tions. The ditîerences are expressed as percentages.
