Abstract

Enthalpies of solution of LiCl and of LiCl · H₂O in water at 298.15 K were measured. Results with different procedures of sample handling are discussed, including the use of the equilibrium between LiCl · H₂O and its aqueous saturated solution as a hygrostat. The molar enthalpies of solution extrapolated to infinite dilution are Δ_solH_m^∞(LiCl, 298.15 K) = -(36653 ± 90) J · mol^-1 and Δ_solH_m^∞(LiCl · H₂O, 298.15 K) = -(18562 ± 54) 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.
