THE TRUE VISCOSITY AND THE COLLOIDAL VISCOSITY [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1926
Abstract There are two kinds of viscosities, viz. the true viscosity and the colloidal viscosity. They can be distinguished by the conductivity measurements. The true viscosity give strong effect on the conductivity but the colloidal viscosity give slight effect on it.
