Limits of the molar-ratio method.
The limiting factors (one constant molar-ratio of metal to ligand, constant excess of masking reagent and buffer, and high enough effective stability) of the molar ratio method are discussed. The lowest values of the effective stability constant for the true metal/ligand ratio to be determined for the complex and for a metal determination to be relatively independent of ligand concentration are calculated.
