Oxichloride of samarium 



SmOCl. 



When oxide of samarium is heated in a current of chlorine it 

 increases largely in bulk, becomes incandescent and is ultimately conver- 

 ted into a white, very hygroscopic powder. 



1.6652 gram of the oxide gave 1.9209 gram of the oxichloride or 

 100 gr. oxide 115.3 gram oxichloride instead of 115.8 gram. 



0.5115 gram gave 0.4418 gram SniaOg and 0.3613 gram AgCl.
