 TABLE X. 



Tables V, IX and the corresponding curves given in Figs. VII, 



VIII, IX, X, and XI, shew that the same effect was noticeable 



throughout until a silver nitrate solution of normality 39.5 x 10"^ was 



reached after which it was not observed, i.e., with concentrations 



above this the conductivity steadily increased with the addition of 



N 

 ^^^p.^ HCl as will be seen from the measurements which are recorded 



in table X and illustrated in Fig. XII. 



Experiment V. — A silver chloride solution was made by adding 



HCl to AgNOg. This was passed through a filter paper, and the 



precipitate washed with distilled water in order to remove the 



hydrochloric and nitric acid. The precipitate was then transferred 



to a beaker containing a small quantity of distilled water. This 



solution was then added drop by drop to 76 cc. of distilled water 



until the conductivity of the resulting solution had increased by an 



amount corresponding to the increase in the previous case with 



AgNOg. Then to this solution of AgCl there was added drop by 



N 

 tlrop a ,„„,,_ solution of HNO„, and the conductivities taken as 

 lOUOU ^ 



before. Tables XI, XII, XIII and the curves given in Figs. XIII, 



XIV and XV shew the variation in conductivity as obtained when a 



N . . . . 



fnono '^'^^^^ ^^'^^^ solution was added to different concentrations of 



the silver chloride solution.
