This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1873 Excerpt: ...the presence of Phosphoric Acid (498). 497. Acidify another portion of the aqueous solution of the ash with nitric acid: add a slight excess of nitrate of silver, and filter the liquid from the white precipitate occasioned by the silver salt. This precipitate may be proved to consist of chloride of silver (hydrochloric Acid), by being readily soluble in ammonia, and insoluble in nitric acid. 498. Accurately neutralize the acid solution formed in (497), with dilute ammonia; the pale yellow phosphate of silver (3 AgO, PO6), which had been held in solution by the excess of acid, will now be precipitated, showing the presence of Phosphoric Acid (496).1 499. The earthy portion of the ash, which proved insoluble in water (491), may now be examined. It is to be dissolved in as small a quantity as possible of dilute hydrochloric acid, a gentle heat being applied if necessary. If effervescence occurs on the addition of the acid, Carbonic Acid is present (489). 500. A little of the acid solution may now be nearly neutralized with dilute ammonia, which should not be added in sufficient quantity to cause any precipitate. The liquid is then tested with a drop or two of a solution of ferrocyanide of potassium, which will cause, either at once or in the course of a few minutes, a blue color, owing to the formation of the ferrocyanide of iron (Fe4Fcy3), showing the presence of Iron. 501. The rest of the acid solution of the earthy portion of the ash may now be supersaturated with ammonia, which will throw down a white gelatinous precipitate of earthy phosphates. A little of this precipitate may be examined under the microscope, when it will be found to consist chiefly of amorphous particles of phosphate of lime (3CaO, PO5), with a few crystals of the double phosphate of ammo.
