Abstract

Gravimetric method is used to measured hydroquinone solubility in water, ethanol and in water+ethanol binary mixtures at temperatures (293.15, 295.15, 298.15, 300.15, 303.15, 305.15, 308.15, 310.15 and 313.15)K. Mole fractions solubility of hydroquinone are correlated with temperature by using the Apelblat equation. The combined nearly ideal binary solvent (NIBS)-Redlich-Kister equation is used to fit experimental hydroquinone solubility data in mixed solvents at constant temperature. AH°Soin, AG°Soin, and AS°Soin are thermodynamic functions of hydroquinone in different solvents, obtained from the modified van't Hoff equation. FTIR study is done for some hydroquinone solution.
