Densities and viscosities of chromium trioxide + potassium chromate + potassium dichromate + water quaternary mixtures and potassium chromate + potassium dichromate + water ternary mixtures have been measured from (298.15 to 333.15) K. The dependence of density and viscosity on temperature and concentration has been correlated. Apparent molar volumes, standard partial molar volumes, and the viscosity B-coefficient of chromium trioxide were calculated from the experimental measurements. The solute-mixed solvent interaction, solute-solute interaction, and structure-making effect of chromium trioxide have been discussed using the Helper equation and the Jones-Dole equation. The relationship between relative changes in viscosity and solute-mixed solvent interaction has been probed.
