IMG:content-0900.png:[blocks in formation] IMG:content-0901.png:[blocks in formation] tenaceous metal, which sometimes occurs native. It does not decompose water at red heat, nor oxidize in dry air; at red heat it oxidizes to a black oxide. Heated with strong sulphuric acid, So is liberated and cupric sulphate formed. It is easily di olved by nitric acid, No2 being given off and cupric nitrate formed. Copper forms several alloys. Bra is an alloy of two-thirds copper and one-third zinc; bronze, gun-metal and bell-metal are alloys of copper with tin. Copper forms sets of compounds, handle. It is used for soldering. If not previously the cuprous and cupric salts. [CUPRIC, CUPROUS, tinned, it is heated to a dull red in a charcoal fire; and their compounds.] Copper pyrites is a cuproso- ferric sulphide. Copper arsenite, or Scheele's green, rubbed immediately upon a lump of sal-ammoniac, is used as a pigment for wall papers, .; it is very and next upon a copper or tin plate, on which a few are known. Copper salts are detected by giving in pletely coat the lace behiped com poisonous. Compounds of copper with ammonia drops of solder have been placed. This will com- an acid solution a black precipitate with H2S. By with a piece of tow, and will then be ready for use. giving a blue precipitate with KHO it becomes black on boiling. When a piece of clean steel is copper blende, s. placed in a solution, copper is deposited on it. Am- monia gives a blue precipitate, which di olves in exce , forming a dark-blue solution. Pota ium ferrocyanide gives a red-brown precipitate of ferro- cyanide of copper, which is soluble in ammonia, forming a blue solution. All salts of copper are poisonous. Verdigris is an acetate of copper, often formed by cooking food in copper ve els. 3.

Hardne , 2.5-3; specific gravity, 8-8-9 or more; color, copper-red streak metallic, fracture hackly. Compos. Copper, pure or with a slight admixture of silver, bismuth, . It is found in beds and veins, chiefly near volcanic dykes, in serpentine, ., or loose in the soil. It occurs at Redruth and at Wheal Buller, ., in Cornwall; in the Ural Mountains and Siberia, China and Japan, near Lake Superior, in Bolivia, Brazil, and Chili.
