Most of the reactions that occur in solutions are of chemical or biological in nature. The ion-solvent, ion-ion and solvent- solvent interactions play a very important role in understanding the physico-chemical properties of solutions. The various interactions mentioned above which are closely akin to ionic solvation, can be studied from different angles using the available technique such as density, viscosity, conductance and ultrasonic speed etc. The knowledge of various interactions of different electrolytes prevailing in different solutions media is capable of indicating the potential usefulness in various technologies such as non-aqueous battery and ion-exchange etc. That why, the present research work demands a great application in modern technology.
