NICKEL NITRATE. 



The freezing-point lowerings produced by solutions of nickel nitrate were 

 studied pretty thoroughly by Jones and Getman.* Their investigations, 

 even on freezing-point lowerings, have, however, been extended to somewhat 

 greater concentrations. The hydrating power of nickel nitrate is of the same 

 order as that of cobalt nitrate (see fig. 51), just as we should expect, since 

 it has the same number of molecules of water of crystallization. Here, also, 

 we notice that the number of molecules of water combined with one molecule 

 of the salt increases from the most concentrated to the most dilute solution.
