Chapter 9.5: Enthalpies of Solution - Chemistry LibreTexts
Two other kinds of changes that are accompanied by changes in enthalpy are the dissolution of solids and the dilution of concentrated solutions. The dissolution of a solid can be described as follows: solute(s) + solvent(l) → soulution(l) (9.5.1) (9.5.1) s o l u t e ( s) + s o l v e n t ( l) → s o u l u t i o n ( l) The values of Δ Hsoln ...

17.13: Heat of Solution - Chemistry LibreTexts
The molar heat of solution (ΔHsoln) ( Δ H soln) of a substance is the heat absorbed or released when one mole of the substance is dissolved in water. For calcium chloride, ΔHsoln = −82.8 kJ/mol Δ H soln = − 82.8 kJ/mol. Figure 17.13.1 17.13. 1: Chemical hot packs and cold packs work because of the heats of solution of the chemicals ...

Hans Peter Jørgen Julius Thomsen
Hans Peter Jørgen Julius Thomsen (16 February 1826 – 13 February 1909) was a Danish chemist noted in thermochemistry for the Thomsen–Berthelot principle Colding, who was one of the early advocates of the principle of conservation of energy, Thomsen did much to found the field of thermochemistry. wikipedia.org
