HYDRATES IN AQUEOUS SOLUTION. 



AMMONIUM CUPRIC CHLORIDE. 



Having studied a large number of the salts of simple acids, we extended our 

 work so as to include a few salts of complex acids. We selected the double 

 chloride of ammonium and copper, since it could readily be obtained in pure 

 condition. When the double chlorides dissolve in water they break down, 

 for the most part, into the single salts, as had been shown by Jones and 

 Knight.* The power to combine with water would then be essentially the 

 power of the single salts to combine with it in the presence of one another.
