The penicillamine–In(III) system has been investigated with potentiometric titration over a wide range of metal concentration at 21°C and <I>I</I>=0.1 (KNO<SUB>3</SUB>). In dilute concentration of metal (0.00025–0.0005 M) and ligand (free base), single species (InL and InL<SUB>2</SUB>) are predominantly formed. In higher concentration of metal (0.0025–0.005 M) and ligand (with an equimolar HCl), the protonated and hydrolyzed complexes (InLH, InL(LH), and InL(OH)) are also formed together with the simple species. The formation constants calculated with non-linear least-squares program were found to be: logβ<SUB>110</SUB>=15.330, logβ<SUB>120</SUB>=29.789, logβ<SUB>11−1</SUB>=18.858, logβ<SUB>12−1</SUB>=33.391, and logβ<SUB>111</SUB>=11.25 for InL, InL<SUB>2</SUB>, InLH, InL(LH), and InL(OH) species, respectively. The formation constants and ultraviolet spectra indicate that the proton in the protonated complex is attached to the amino-group of penicillamine.
