Solubility data for potassium dichromate in dilute aqueous methanol and 2-propanol solutions and the densities of the saturated solutions at the equilibrium temperature were determined at five temperatures (283, 288, 293, 298, and 303) K. The solubility data were correlated with the empirical equation In X1= A + Bxi at temperatures (283, 288, 293, and 298) K and In x1=A + Bxi + Cxi2 at 303 K, where X1 are the mole fraction of potassium dichromate and Xi the mole fraction of methanol or 2-propanol in salt-saturated solutions and A, B, and C are fitted empirical constants depending on the temperature. The precision of the fitted correlations are less than ±0.7% for both methanol and 2-propanol aqueous systems.
