  • Abstract

    Interionic interactions of ternary mixtures of sucrose in aqueous alkali metal halides namely, sodium chloride (NaCl), potassium chloride (KCl), potassium bromide (KBr) and potassium iodide (KI) at 303.15, 308.15 and 313.15K was studied in this paper. For this, binary solvent mixture (water+ metal halides) was prepared at two molalities (m) (Say, at 0.0 m and 0.3 m). The related and relevant parameters correlated to the present study such as adiabatic compressibility (β), apparent molal compressibility (φK), apparent molal volume (φV), limiting apparent molal compressibility (φKo), limiting apparent molal volume ((φvo) and their associated constants (SK, SV), partial transfer volume (Δφvo) from water to aqueous solution and viscosity B-coefficient of Jones-Dole equations were meticulously evaluated to interpret the results in terms of interionic interactions such as solute-solvent, solute-solute, ion-solvent, ion-ion etc, existing in the solution.
