title: The possibility and accuracy of potentiometric equilibrium studies at very high ligand to metal concentration ratios.
abstract: The possibility and accuracy of potentiometric equilibrium studies are analysed by use of the rules of the implicit function-systems for the mass-balance equations. The conditions necessary for the use of potentiometry at very high ligand to metal concentration ratios are briefly outlined. The effect of the total ligand (glycine) concentration on the measured pK is studied experimentally and interpreted in terms of the change in the difference in diffusion potential between the reference half-cell and the solution.
