WebNov 3, 2024 · Hydration enthalpy is the enthalpy change when one mole of gaseous ions become aqueous ions . ... Calculate the enthalpy of solution of NaClgiven that the lattice enthalpy of formation of is - 771 kJmol-1 and the enthalpies of hydration of sodium and chloride ions are -406 and -364 kJmol-1 WebEnthalpy change of hydration. The lattice energy (ΔH latt ꝋ) of KCl is -711 kJ mol-1This means that 711 kJ mol-1 is released when the KCl ionic lattice is formed; Therefore, to break the attractive forces between the K + and Cl-ions, +711 kJ mol-1 is needed; However, the ΔH sol ꝋ of KCl is +26 kJ mol-1; This means that another +685 kJ mol-1 (711 - 26) is …
