TABLE III. 



The above tables and the curves plotted in Figs. Ill, IV and V, 



N 

 shew that on the addition of the first few drops of TKKnh ^^1 there 



was very little change in the conductivity of the solution, but as the 

 HCl solution became more concentrated the conductivity gradually 

 increased. 



Experiment IV. — To 75 c.c. of redistilled water there was added a 



^^^P^lw c-*^^"-) ^^ Tfïï^ AgNOg, thus giving a 4.94 x 10-^ normal 



solution of silver nitrate. To this solution was added, drop by 



N 

 drop, a ^ solution of HCl. The variation in conductivity for 



different concentrations of the hydrochloric acid is shewn by the 

 numbers in tables IV, and the curve in Fig. VI.
