Exploration of Solution Behaviour of Potassium Halides in Mixtures of LProline and Water at 298.15, 308.15 and 318.15 K

Mahendra Nath Roy, Partha Sarathi Sikda, Pritam De

Apparent molar volume ( φ_V ) and viscosity B-coefficients were estimated for potassium chloride, potassium bromide and potassium iodide in aqueous mixture of L-Proline from measured solution density (ρ) and viscosity (η) at 298.15, 308.15 and 318.15 K at various electrolyte concentrations. The experimental density data were evaluated by Masson equation and the derived data were interpreted in terms of ion-solvent and ion-ion interactions. The viscosity data has been analyzed using Jones-Dole equation and the derived parameters, B and A, have also been interpreted in terms of ion-solvent and ion-ion interactions respectively. The structure-making or breaking capacity of the electrolyte under investigation has been discussed in terms of sign( ∂φ_V⁰ / ∂_T )P.
