    pliuretted hydrogen gns (sec page 360) through water of ammonia till the liquid occasions no precipitate in a solu- tion of sulphate of magnesia. Solution of Ammonia-nitrate of Silver. To a solution of nitrate of silver (1 part of crystallized nitrate to 20 of distilled water) add gradually weak water of ammonia till a mere trace of the oxide first precipitated is left undis- solved. Let it settle, decant it into a clean stoppered bottle, and keep it from the light. The Edinburgh Phar- macopoeia directs 44 grains of nitrate of silver to be dis- solved in a fluid ounce of water, and sufficient ammonia added, as above. [It gives a pale yellow precipitate with arsenious acid, and a chocolate red with arsenic acid j the same with their salts.] Solution of Nitrate of Silver. The Edinburgh Phar- macopoeia directed this test to be prepared by dissolving 40 grains of the nitrate in a fluid ounce of distilled water. The London Pharmacopoeia directed 60 gr. to a fluid ounce. Mr. Parnell recommends 1 part to 15 or 20 of water. [It is used chiefly for the detection of chlorine or hydro- chloric acid. The precipitate, chloride of silver, is insoluble in nitric acid. Also for hydrocyanic acid, with which it gives a white precipitate, which is decomposed by heat, the silver being reduced.] Solution of Ammonio-sulphate of Copper. Dissolve 1 drachm of sulphate of copper in 2 oz. of water, and add ammonia till the precipitate first thrown down is nearly all dissolved. Let it settle, and pour off the clear solution. [Chiefly used as a test for arsenical compounds, with which it gives a green precipitate.] ,Solution of Chloride of Barium. Dissolve 60 grams of the chloride in a fluid ounce of distilled water. Solution of Nitrate of Barytes. (Ed. Ph.) Dissolve 40 grains of nitrate of barytes in 800 grains of distilled water. , Solution of Indigo. Digest 1 part of fine indigo m 10 parts of oil of vitriol, and dilute with water. For the Test Solutions of the P. P., see P. F. Hahnemann’s Wine Test, for detecting lead in wine.
