HYDRATES IN AQUEOUS SOLUTION.

COBALT NITRATE. 



The nitrate of cobalt, like the chloride, crystallizes with 6 molecules of 

 water of crystallization, and we should expect hydrating power of the same 

 order of magnitude. Such is the fact. Jones and Bassett worked with more 

 concentrated solutions than had been previously used, and supplemented the 

 data obtained by Jones and Getman* for all of the solutions, so as to be able 

 to calculate the composition of the hydrates at the various dilutions. The 

 regular increase in the amount of water held in combination, with increase 

 in the concentration of the solutions, is shown by the curve in fig. 51.
