Concentration 



Fig. 13. Curves representing the attraction of different aluminium salts for 

 negatively charged particles of water. The attraction is a maximum in the 

 case of AlaCIe, is less in the case of Al2(S04)3, and is practically lacking in the 

 case of aluminium citrate, showing the increase in the repelling effect of the 

 anion upon the negatively charged particles of water with increasing valency of 

 the anion.
