Abstract
The viscosity of potassium chloride-glucose-water ternary system with varying concentrations was
investigated in this study. The density of the ternary system was measured with a Gay-Lussac-type
pycnometer. The flow time of the ternary system was measured with an Ubbelohde viscometer. The viscosity
of the solutions was calculated from the density and the flow time. All measurements were conducted at 25.0
± 0.01°C. The viscosity curve is not simple. It decreases at lower KCl concentration then increase
gradually with increasing KCl concentration. The tendency is emphasized with increasing glucose
concentration. An increase or decrease in the dependence of viscosity on KCl concentration is seen in the
binary KCl-water system as a function of temperature.
