【摘要】 本文根据离子极化原理,探讨了络合物稳定性的规律,得到了计算络合物稳定常数的公式: log K_r=AZ²/r+BX_±+C,此处,Z是阳离子电荷,r是阳离子半径,X_±=（X_-+X₊）/(X_--X_?),称为电负性和差比。A、B、C在确定配位体之后是常教,其值可根据已知的log K₁、Z²/r及X_±值用荔枝Ⅱ微电脑算出。在此基础上,本文还讨论了影响络合物稳定性的因素,并例举了一些在分析上应用的实例。更多还原

【Abstract】 The theory of ion polarization is proposed for studying the rules of complex stability. An equaequation is derived for the calculation of the stability constant of coordination compoundslogK₁=AZ²/r+BX_±+C where A, B, C, are empirical constants, Z is cation charge, r is cation radius, X_±= （X_-+X₊）/（X_--X₊）, while X_- and X₊ are electronegativities. Basing on this, equation. the factors influencing the stability of metal complexes and some uses of coordination in analytical chemistry are discussed.更多还原
