MAGNESIUM BROMIDE. 



The bromide of magnesium, like the chloride, had already been studied 

 by Jones and Getman.* They were interested especially in the magnitude 

 of the hydration in concentrated solutions. Much of the data necessary 

 to calculate the approximate composition of the hydrates, in dilute solution, 

 had to be secured by Jones and Bassett. The results for magnesium bromide 

 are very similar to those for magnesium chloride. The amount of water 

 held in combination is larger than in the case of any bromide of the calcium 

 group. We notice here, also, a regular increase with the concentration in 

 the value of m'(see fig. 48). Here, again, the number of molecules of water 

 combined with one molecule of the salt increases from the most dilute to the 

 most concentrated solution.
