Hydrous Aluminum Chloride. 



Pure hydrous aluminum chloride, A1C1 3 -6H 2 0, was made by 

 dissolving the C. P. hydrous chloride of the laboratory in the 

 least possible amount of aqueous hydrochloric acid, filtering 

 the solution through asbestos, and saturating the clear solution 

 with gaseous hydrogen chloride. The crystallized chloride 

 thus obtained was collected on asbestos in a perforated cone,
