Abstract: Eight methods have been proposed for the estimation of stability constants of complexes as follows;1.lgK1=Az2/r+Bx±+C.2.The linear relationship between lgK1of two similar metal ions with a series of ligands.3.The linear relationship between lgK1of two similar ligands with a series of metal ions.4.The linear relationship between lgK1and ∑pKafor complexes of one metal ion with a series of similar ligands.5.The linear relationship between lgK1and x± for a series of metal ions with similar z2/r.6.The linear relationship between lgK1and z2/r for a series of metal ions with similar x.7.The stability constants show the same "normal" variation as z2/r and x for the metal series.8.Ligands with larger∑pKabind strongly to metals with larger z2/r and ligands with smaller x bind strongly to metals with larger xEight methods have been proposed for the estimation of stability constants of complexes as follows;
