BARYTES AND BARIUM. 269 



pound of 1 atom oxygen and 1 atom hydrogen, 

 and its atomic weight is 1/1&5. 



4. An integrant particle of anhydrous muriate Muriate of 

 of barytes weighs 14-375 ; being composed of 



1 atom muriatic acid 4-625 

 1 atom barytes 9-7 5 



14-375 



5. When muriate of barytes is exposed to a red 

 heat, it undergoes a double decomposition. The 

 hydrogen of the acid and the oxygen of the base 

 uniting together, constitute a particle of water, 

 which is driven off by the heat, while the chlo- 

 rine and the barium remain united together in 

 the state of chloride of barium. For it is obvi- 

 ous, that 14-375 of muriate of barytes may be 

 decomposed into 



1 atom water = 1-125 



1 atom chloride of barium 13-25 



14-375 



6. Whenever chloride of barium is dissolved in 

 water it is again converted into muriate of ba- 

 rytes. A portion of the water is decomposed, 

 the hydrogen of which converts the chlorine into 

 muriatic acid, while the oxygen changes the ba- 

 rium into barytes. 



7. Thus, it appears, that whenever muriate of 

 barytes is exposed to a red heat, it is converted
