氧化物酸碱性的离子参数标度法

A method of scaling acidity and alkalinity of oxides with ion parameters

采用离子参数电离势I及有效核电荷数Z*与离子半径R之比Z*/R来标度氧化物的酸碱性,建立了新的氧化物离子参数函数A=I+1.24Z*/R-38.87;通过计算可确定氧化物的A值,作为新的标度值可以衡量氧化物酸碱性的相对强弱,所得结果与实际情况相吻合;而且还可以预测氧化物的酸碱性,对于推测氧化物的化学性质有一定指导意义.

Based on the relationship between acidity and alkalinity of oxides and ion parameters, some ion parameters,such as elemental ionization power I, effective nuclear electricity Z^＋ and ionic radius R. Were selected to scale acidity and alkalinity of oxides,and the ionic parameter function, A= I＋ 1.24 Z^＋/R-38.87, was established. Though calculation the A values were obtained,which can measure the relative strength of acidity and alkalinity of oxides, and the results coincide with the actual situations. As a new method, it can predict and measure the relative strength of acidity and alkalinity of oxides ,and acid and alkali of the oxide can be definited.
