| Cupric Carbonate is also called Copper(ii)Carbonate Basic.It is peacock-green minor amorphous powder.Specofic gravity is 3.85 Cupric Carbonate is not solude in cold water or alchol.And soluble in acid,cyanide,ammonium liguor and sodium alkali,ammonia salts.When Cupric Carbonate is boiled in alkalind metal Carbonate solution brown Cupric Oxide will be formed, and it will decompose into black Cupric Oxide below 200°C,Cupric Carbonate will be unstable under hydrogen sulfide atmosphere.There are ten plus kinds of Cupric Carbonate compounds because of varying rates of CuO:CO2:CO.Molecular formula is CuCO3·Cu(OH)2·XH2O solubility in water is 0.0008%.The decomposition temperature is 200-220°C.Cupric Carbonate is low texic. |
