NICKEL CHLORIDE. 



The earlier work of Jones and Getman* had to do only with the more 

 dilute solutions of nickel chloride. The earlier work was extended from a 

 concentration of only 0.743 N to 3.483 N. The results with nickel nitrate 

 are similar to those with cobalt chloride. The amount of water combined 

 with the salt in solution increased regularly from the most dilute to the 

 most concentrated solution (see fig. 50) . The number of molecules of water 

 combined with one molecule of the salt increases, fairly regularly, from the 

 most concentrated to the most dilute solution.
