Precipitation of Basic Copper Carbonates From Cupric Sulphate and Sodium Carbonate Solutions

Precipitation of Basic Copper Carbonates From Cupric Sulphate and Sodium Carbonate Solutions

The  effect of the mBasic Copper Carbonate(WSDTY)olecular ratio Na2CO3/CuSO4, concentration of the reacting solutions, mode of agitation during precipitation, and ageing of the precipitate on the chemical composition and physical properties of the products from mixing aqueous solutions of copper sulphate and sodium carbonate was investigated. For products of definite chemical composition and desirable physical properties, the recommended precipitation conditions are: molecular ratio Na2CO3/CuSO4, 1.1:1; concentration of reacting solutions, approximately 1.0 molar; mild stirring; and sufficient time must be allowed for the precipitate to transform from blue gelatinous to green crystalline form. The CuO/CO2 ratio in the precipitates thus obtained correspond with that of malachite.
