Abstract:
The physical properties such as viscosity and metal-bonding stability constant in 70% DMSO-Water and refractive index and polarazibility constant in different concentration with pyrazoles and diketones at 300c. The results obtained of stability constant are in good agreement. Measurements of refractive index have been studied by Abbe’s refractometer. Molar refractivity and polarazibility constants of ligands solution have been evaluated in the present investigation. It could be seen that molar refractivity and polarazibity constants are found to be decreased with increase in density of solution.The stability constants of metal-ligand complex formation of Co(II) and Ni(II) with pyrazoles and diketones have been studied using Irving Rassoti’s Method and titration is done by using Calvin BjerrumMethod in an inert atmosphere at 0.1M ionic strength and temp.(300c± 0.10c) pH metrically.
KeyWords: Substituted Pyrazoles and Diketones, Molar Refractivity and Polarazibity constant, metal-bonding stability constant, DMSO.
