- In this paper,the rule of polarization for metal ions has been extended to the hydrolysis reactions. The empirical formula was found as: pK_1=a~(Z*)/r 1/2+b where the parameter r is equalto the ionic radius plus the radius of the oxygen atom in water. 本文甩参数 z~%23/r~(1/2)来总结金属离子水解的规律性,得到经验方程:pK_I=b-az~%23/r~(1/2),r 为金属离子半径与水分子半径之和,可以认为是极化作用半径。
