Density and viscosity of tetrabutyl ammonium hydrogen sulphate and tetrabutyl ammonium chloride salts in aqueous and methanolic solution at 303 K

Density and viscosity of tetrabutyl ammonium hydrogen sulphate and tetrabutyl ammonium chloride in water as well as in methanol have been measured at 303.15 K. Different equations proposed by Einstein, Vand, Moulik and Jones?Dole for viscosity have been applied to the experimental results. An attempt has also been made to study the solute?solute and solute?solvent interactions involved in the system and the effect of anion on cationic surfactant. Molar volumes obtained from Einstein and Vand equations are very close to each other.
