极化力参数与金属离子水合热的关系研究

Studies on correlation between the polarizable ability parameter and hydrated heat of metal ions

用有效主量子数n*、电负性I、离子电荷数Z,定义一个极化力参数T,T与51种金属离子的水合热ΔrH0h呈现高度的相关性,它们的线性回归方程为:ΔrH0h=-64.92+819.41T,r=0.9968.该模型原理简单、结果可靠、物理意义明确,其预测值与实验值吻合良好,且置信度高达99.9%.

The polarizable ability parameter T is defined by means of effective principle quanturnnumber n^＊ , electronegativity I and electric charge number Z of metal ion. T has highly correlativityfor hydrated heat of metal ion. The linear regression equation is proposed as follows：△rHh^0 = - 64.92 ＋ 819.41 T, r = 0. 9968. The results showed that the model has the advantage of principlesimple, results credibility and clear physical significance, and confidence degree high to 99.9 %.
