WebIn thermochemistry, the enthalpy of solution (heat of solution or enthalpy of solvation) is the enthalpy change associated with the dissolution of a substance in a solvent at constant pressure resulting in infinite dilution.. The enthalpy of solution is most often expressed in kJ/mol at constant temperature. The energy change can be regarded as being made of … WebWe have to use double the hydration enthalpy of the chloride ion because we are hydrating 2 moles of chloride ions. Make sure you understand exactly how the cycle works. So . . . ΔH sol = +2258 - 1650 + 2 (-364) ΔH sol = -120 kJ mol -1. Whether an enthalpy of solution turns out to be negative or positive depends on the relative sizes of the ...
