MURIATES AND CHLORIDES. 



of 1 atom chloride of barium and 2 atoms water, 

 or of 1 atom of anhydrous muriate of bary tes 

 and 1 atom water. From the phenomena which 

 take place when barytes is dissolved in muriatic 

 acid, I adopt the second hypothesis as the 

 simplest ; indeed, whenever a salt belonging to 

 this genus contains water of crystallization, I 

 conceive it to be simplest, and therefore best to 

 consider it as a muriate. A red heat, if it can 

 resist such a temperature, not only drives off all 

 the water of crystallization, but causes the hy- 

 drogen of the acid to unite with the oxygen 

 of the base, and to fly off likewise in the state of 

 water, leaving the salt in the state of a chloride. 

 For it is worthy of remark, that whenever the 

 base is a deutoxide, the salt contains two atoms 

 of muriatic acid or is a bimuriate. 



Muriate 4. Muriate of strontian. This salt crystallizes 

 in very long white needles, which when viewed 

 by the microscope have the form of hexagonal 

 prisms. It is more soluble in water than mu- 

 riate of barytes, and likewise soluble in alcohol, 

 which muriate of barytes is not. Its constituents 

 are 



1 atom muriatic acid 4-625 

 1 atom strontian 6'5 



8 atoms water 9 



20-125 



When 20-125 of it are heated, they lose 10-125
