COBALT CHLORIDE. The cobalt chloride used in this work was obtained from Kahlbaum. No appreciable impurity could be detected. This salt can not be dehydrated in contact with the air, and special precautions must be taken to prevent the formation of the oxychloride. The salt containing 6 molecules of water was first placed over concentrated sulphuric acid, in a vacuum desiccator, for several days. It was thus deprived of part of its water of crystallization. It was then placed in an air-bath and dried at 140° to 150°, in a stream of dry hydrochloric acid gas. The salt was subsequently kept in a vacuum desic- cator over sulphuric acid and potassium hydroxide. It gave no test for free hydrochloric acid, and possessed a pale, sky-blue Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
