Abstract
Abstract The reactions of 2-amino-2(hydroxymethyl)-1,3-propanediol (TRIS, THAM) with H+, Ni2+, Cu2+, and Zn2+ ions have been studied at 298 K in aqueous solutions (0.15 mol dm−3 NaCl) using ptentiometric techniques. The protonation constant of the ligand and the formation constants of several metal complexes have been calculated with the aid of the program MIQUV. The equilibrium models are selected on the basis of a critical evaluation of the least squares results and of a statistical analysis of the wieghted residuals.
