A STUDY OF VISCOSITY OF AQUEOUS SOLUTIONS OF POTASSIUM DICHROMATE

Viscosity of aqueous solutions of potassium dichromate over a wide range of concentrations up to satoration has been determined at temperatures ranging From 30' to 60°. The variation of viscosity with temperatures at any given concentration has been found to obey Andrade's exponential equation. The variation of viscosity with concentrations at any given temperature has been found to obey another exponential equation, first observed by Surayanarayana and Venkatesan.
