ABSTRACT
The solubility of 2,7-dihydroxynaphthalene in binary sodium chloride + water, sodium sulfate + water, and ethanol + water solvent mixtures was measured in the temperature range from (283.15 to 328.25) K by a steady-state method. The results of these measurements were correlated by a modified Apelblat equation.
