Study of Solute-Solute and Solute-Solvent Interaction of Sodium Dodecyl Sulfate and Cetyl Pyridinium Bromide in Aqueous Medium

Abstract

The density, viscosity and apparent molar volume (φ_v) of sodium
dodecyl sulfate (SDS) and cetyl pyridinium bromide (CPB) in aqueous
solution at 298.15 K are reported. The experimental results of
viscosity and density have been analyzed using Jones-Dole and
Masson equations. respectively. The values of constants A and B
of the Jones-Dole equation and those of  φ_v and S_v of Masson
equation are explained in terms of solute-solute and solute-solvent
interactions. The data indicate that there is negligible solute-solute
interaction and strong solute-solvent interaction.
