WebPublished stability constants are conditional in the sense that they refer to a particular temperature an, in most cases, to a particular strength of a particular ionic medium. Cumulative and stepwise constants A cumulative or overall constant, given the symbol β, is the equilibrium constant for the formation of a complex from reagents. Webvalues of stepwise formation constants may be attributed to the decrease in the number of coordinated H 2 O ligands that are available for the replacement by the attacking ligands. Besides, the continuous decline in the values of successive stepwise stability constant values may also be attributed to the decreasing ability of metal
