Measurement and prediction of densities, viscosities, and surface tensions for aqueous solutions of potassium citrate

Densities and viscosities of aqueous potassium citrate (PC) solutions have been determined at 293.15, 303.15, 313.15 and 323.15 K. Surface tensions of aqueous PC solutions have been measured at 293.15 K. Physical properties of aqueous PC solutions were correlated with the measured data in this work. The densities, viscosities and surface tensions of the PC solutions increase as the PC concentration increases. Densities, viscosities, and surface tensions of aqueous PC solutions have been correlated with molality and temperature. The correlation equations for each physical property can offer additional data for aqueous solutions of PC.

► New and accurate data of three physical properties of aqueous potassium citrate have been measured.
► Additional data can be obtained by using the correlation coefficients.
► Data can be used for theory calculations and engineering designs.
