Enthalpies of Dilution and Excess Molar Enthalpies of an Aqueous Solution of Sulfuric Acid

Abstract

The enthalpies of dilution of the binary system H2SO4 + H2O have been measured at the temperatures of (283.15, 293.15, 313.15, and 333.15) K using two different calorimeters. The excess molar enthalpies, HE, of the system H2SO4 + H2O are obtained from the enthalpies of dilution data. The enthalpies of dilution and the HE data are reported and compared to literature values.
