Arsenic disulfide (AsS) is also known as ruby arsenic because it is a reddish-orange powder. It is used as a depilatory agent, a paint pigment, and a rat poison and to make red glass and fireworks. 

Lead Metarsenate, Pb(As03)2, is obtained by heating a mixture of arsenic pentoxide and lead monoxide, red lead or lead nitrate in suitable proportions.9 A transparent glass is formed which, if broken up and heated to incipient fusion, crystallises as hexagonal tablets of density 6-42. The salt is decomposed by water. 

When the apparatus is assembled, the Wolff s bottle is placed half in cold water and is charged with pure zinc and dilute sulphuric add (1 part of cone, add + 4-5 parts of water), the evolution of hydrogen being allowed to proceed until all the air is expelled from the apparatus. The hard glass tube is then heated to redness with a bunsen flame about 10 cm. wide to ascertain if any shining grey or black ring forms at the constricted part if not, the freedom of the zinc and add from arsenic is presumed and the actual test made. 

The phosphides, arsenides, and antimonides of the other metals are usually dark-coloured substances, with more or less metallic lustre, and therefore conductors of electricity. Some of them occur native for example, smaltine, CoAs2, a common ore of cobalt, forming silver-white crystals copper-nickel, NiAs, red lustrous crystals, and one of the chief nickel ores speiss, a deposit formed in the pots in which smaltine and copper-nickel are fused with potassium carbonate and silica, in the preparation of smalt, a blue glass containing cobalt its formula appears to be Ni8As2. Mispickel, or arsenical pyrites, is a white lustrous substance, of the formula FeSAs.
