HYDRATES IN AQUEOUS SOLUTION. 



COPPER CHLORIDE. 



In the paper* to which reference has already been made, Jones and Get- 

 man attempted to calculate the approximate composition of the hydrates 

 formed by copper chloride. In this calculation they had to make use of a 

 part of the data obtained from other sources. Jones and Bassett have 

 supplied this data for the various solutions, especially the specific gravities. 

 They encountered difficulty in determining //oo for the copper salt. The 

 value given was obtained by the conductivity method, taking into account 

 the hydrolysis of copper chloride in dilute solutions. 



The hydrating power of copper chloride is larger than would be expected 

 from its water of crystallization.
