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. 1867 Excerpt: ...with fluxes, the reaction of iron and copper. Arsenical Copper Domeykite. 140. Cu6As. H=3--3.5. Reniform, massive, or disseminated; lustre metallic; color tin-white; black and soft when impure. Heated in a matrass, yields a little water and a sublimate of arsenous acid; the assay-piece assumes a silver-white color. In an open tube, affords a crystalline sublimate of arsenous acid. On Ch, fuses easily with emission of a strong alliaceous odor to a yellowish metallic mass, which gives the copper reactions. Readily soluble in nitric acid; decomposed by hydrochloric acid, metallic arsenic remaining undissolved. Atacamite. 141. CuCl+3CuO + 3HO. H=3--3.5. G=4--4.3. Occurs crystalline, or massive lamellar; color various shades of bright green, sometimes blackish-green. Heated in a matrass, gives out water and a gray sublimate, which, on cooling, becomes grayish-white; the water shows acid reaction. On Ch, fuses readily, colors the outer flame azure-blue, and is finally reduced to a globule of metallic copper; two coatings are deposited on the Ch, the one grayish-white, and the other brownish, which, on being played upon with the R Fl, change their place with an azure-blue tinge. Easily soluble in acids. Red Copper. 142. Cu20. H=3.5--4. G=5.8--6. Usually of a very intense, deep red color, occasionally crimson-red; exceedingly friable. Heated in the pincers, fuses and colors the outer flame emeraldgreen; moistened with hydrochloric acid and treated in the same manner, the color is azure-blue. On.Ch it blackens, then fuses quietly, and finally yields a globule of metallic copper which, on cooling, becomes covered with a coating of black oxide. Dissolves readily in nitric acid. With hydrochloric acid it gives a brownish solution, which on addition...
