Abstract

From the distribution constants of ammonia (ammonium hydroxide) in water and chloroform, the interaction solvation parameters with nano copper sulfate was studied at 29.15K. The distribution constant K, coordination number for copper ammonia complex, equilibrium reaction constant K eq and Gibbs free energies of solvation were evaluated for this reaction. All the data were done five times and compared with that by using normal copper sulfate. The aim of this work is to compare between the different solution behavior for nano CuSO₄ and normal one in copper ammonia complex formed in aqueous layer.
