Not illustrated. 1870 edition. Excerpt: ...taken. It identifies hydrochloric acid by producing in solutions which contain it, or its salts--that is, the chlorides--a white precipitate of the chloride of silver, AgCl, which is distinguished from other similar substances by being perfectly soluble in ammonia, but quite insoluble in nitric acid. The yellow colour of the commercial acid may be due to dissolved organic matter, but more generally to the presence of the chloride of iron. The latter may be indicated by diluting the acid with water, and adding a solution of ferroc/anide of potassium, which gives more or less of a blue colour, according to the quantity of iron. 587. Aqua regia is a mixture generally of two parts of hydrochloric acid and one part of nitric acid, and is employed in dissolving gold, platinum, and other substances. Oxides of Chlorine. 588. There are five oxides of chlorine, which are possessed of some interest. Three of these compounds can be obtained in a separate state. Atomic or Symbols. Combining prop0rtion.

Hypochlorous anhydride, G20, is prepared bypassing a stream of chlorine through a tube containing powdered red oxide of mercury; and the hypochlorous acid in its hydrated state, HCI0, is obtained by adding finely powdered red oxide of mercury to a bottle containing chlorine gas and a little water. The bottle is closed with a cork and shaken briskly. The chlorine combines with the mercury to form chloride of mercury, and also with the oxygen to form hypochlorous acid, more
