Electron Donor-Acceptor Interaction Parameters of Calcon Carboxylic Acid with Nano Cobalt Sulphate in Methanol ( Meoh ) - Water at Different Temperatures by Applying Conductance Studies

Abstract

Nanoparticles are incredibly essential for medicine in addition to environment, because of their increased behaviors due to their high surface area and small volume, makes them very reactive. This article summarizes different aspects of the complexes of the nano CoSO 4 with ligand Calcon carboxylic acid (Calcon CA) as studied conductmetrically in mixed methanol-water solvent at 298.15, 303.15, 308.15 and 313.15K by applying the condutometric method. Consequently, we will study the effect of solvent properties, (MeOH/H 2 O) 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 , 1:1 and 2:1 (M:L) stoichiometry complexes.
