【摘要】 本文提出了四种类型常见的微溶化合物溶介度计算的浓度对数图作法及应用示例,即微溶弱酸盐的溶介度与pH关系;微溶氢氧化物溶介度与pH关系;微溶化合物形成络合物而溶介时,溶介度与络合剂浓度关系及微溶化合物可与沉淀剂形成可溶性络合物时,溶介度与沉淀剂浓度关系。 通过实例论证,说明在计算微溶化合物的溶介度时,采用浓度对数图介法,具有作图方便、形象准确等特点。更多还原

【Abstract】 The authors have described the conccniralion - logariihmic diagram method for calculating the solubility of common insoluble compounds,together with their drawing-up and application examples. Four types of the diagram are provided;solubility of insoluble salts of weak acid with pH;solubility of insoluble hydroxides with pH;solubility of insoluble compounds which form soluble complex,with concentrations of complexing agent;and solubility of insoluble compounds which form" soluble complex with precipitant,with,concentrations of precipitant.Practical examples have shown that in the calculation of solubility of insoluble compounds the use of concentration-logarithmic method has the pecularity of being simple,convenient and accurate.更多还原
