| Popis: | The solubilities of Cu2(OH)2CO3 (malachite) and Cu3(OH)2(CO3)2 (azurite) have been studied at 25° C in solutions of the constant ionic strength 0,2 M consisting primarily of sodium perchlorate. From experimental data the following values for equilibrium constants and Gibbs energies of formation are deduced: Predominance area diagrams for the ternary system Cu2+H2O-CO2(g), including CuO, Cu(OH)2, Cu2(OH)2CO3, Cu3(OH)2(CO3)2, Cu2+ and Cu (CO3)22−, are given. |
