摘要：

The solubilities of ZnCO3 and Zn5(OH)6(CO3)2 have been investigated 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 free energies of formation are deduced: (Formula Presented.) (Formula Presented.) (Formula Presented.) (Formula Presented.) A predominance area diagram for the ternary system Zn2+–H2O–CO2(g) including ZnO, ZnCO3, Zn5(OH)6(CO3)2, and Zn2+ is given. Copyright © 1969 Verlag GmbH & Co. KGaA, Weinheim
