This article summarizes different aspects of the complexes of the the nano NiSO4 with ligand (Eosin Y) as studied condutometrically in pure MeOH solvent at 293.15, 298.15, 303.15 and 308.15K by applying the condutometric method. Consequently, we will study the effect of solvent properties, (MeOH) on stoichiometry, the selectivity between ligand and ions in various systems and thermodynamic parameters of complexation. On drawing the relation between molar conductance and the ratio of metal to ligand concentrations, different lines are obtained indicating the formation of 1:2, and 1:1 (M:L) stoichiometry complexes. The stability constant of the complexes were obtained from fitting the molar conductivity curves using a computer program. This research focused on the study of thermodynamic complexation reactions between the ligand, Eosin Y, with Ni2+ metal cation in pure MeOH solvent.
