1966 Kawahara Viscosity and Density of Aqueous Solutions of Urea

Densities and viscosities of aqueous solutions of urea and guanidine hydrochloride at 25 degC have been measured, and equations are presented which describe their variation with concentration. Densities and viscosities of similar solutions containing additional solutes (buffers, NaCI, -mercaptoethanol) have been measured, and the possibility of predicting these results from information on solutions containing each solute separately is discussed.
