| Özet |
| Equilibria of the reaction of molybdenum(VI) with L-aspartic acid (Asp) was studied by spectrophotometric measurements in mixed-solvent systems at an ionic strength of 0.2 mol/l sodium perchlorate, employed (15, 20, 25, 30 ± 0.1°C) at pH ranges of 3.2 to 5.5 with a high ratio of ligand to metal. The stability constants of the complexes and the resulting free-energy changes are presented. The effect of solvent systems on protonation and complexation are discussed. Linear relationships are observed by plotting log K versus 1/D, where K and D show stability and dielectric constants, respectively. |
