Product description

Product English name：Cupric Carbonate Basic
CAS No.： 12069-69-1
Molecular formula：CuCO₃Cu(OH)₂XH₂O
molecular weight：221.12
Properties: amorphous powder malachite green fine particles, the density of 3.852000C decomposition, insoluble in water and alcohol, soluble in acid copper salt and the formation of the corresponding solution, for the aqueous solution of cyanide, sodium hydroxide, ammonium and alkali metal carbonate and the formation of copper complexes. Boiling in alkali metal carbonate solution. Generation of brown copper oxide, decomposed into black copper oxide in 2000C. It is unstable in the atmosphere of hydrogen sulfide. The solubility of the water in the water is 0.0008%, and the decomposition temperature is 200-2200C low toxicity.
