Abstract

Enthalpies of solution of Li₂SO₄ and Li₂SO₄·H₂O in water at 298.15 K were measured. The molar enthalpies of solution extrapolated to infinite dilution are Δ_solH_m^∞(Li₂SO₄, 298.15 K) = - (30502 ± 170) J·mol^-1 and Δ_solH_m^∞(Li₂SO₄·H₂O, 298.15 K) = - (17899 ± 152) J·mol^-1. The value for the monohydrate has been calculated by assuming that the excess water in the sample over the theoretical is present as an aqueous saturated solution. There are presented preliminary specific heat capacities of lithium sulfate solutions.
