Thermodynamic study of Pr(III) complex in mixed solvent system at 303.15K

Abstract

A conductance study of the interaction between Pr(III) complex in mixes solvent system at 303.15K. The metal-ligand stability constant of the complex was determined by conductance measurements. The free energy change of the complex was investigated at 303.15K using thermodynamic relations, the negative values of free energy means that the complex formation process is spontaneously.

Key word: metal –ligand stability constant, conductometry., thermodynamics relations
