reached by the NaCl curve, and the minimum for the citrate and 

 ferrocyanide is still higher. This was to be expected from the fact 

 that the attractive action of the anion upon the positively charged 

 particles of water is higher the greater the number of charges or the 

 valency of the anion.

Figs. 5 and 6. Curves representing influence of different chlorides (Fig. 5) and 

 sulfates (Fig. 6) on initial rate of diffusion of water from pure solvent into solution, 

 showing that the drop is greater in case of Li than of Na, or of K, and supporting 

 the view that the drop is due to the repelling effect of the cation upon the posi- 

 tively charged particles of water.
