摘要
本文提出了一种计算金属和试剂分别过量时形成不同颜色络合物的真正组成、稳定常数以及某些单核与多核络合物并存时平衡体系数学解的方法。
The title method is based on the effect of dilution on the dissociation degree (α and β) of complexes (M_mB_m and M_nB_n). The values of m and n for complexes,the type of M_mB_m and M_nB_n, can be obtained by using the title method and the stability constants (K_1 and K_2) for these two complexes are given as well. Once the correct values of m, n, K_1 and K_2 are known, it is possible to solve the mathematical solutions of their component concentration in some systems. The results for two well-stuided systems, zirconium-xylenol orange and lead-xylenol orange, are shown as the demonstrations.
