For an ionic compound dissolving in water, $\Delta H_{\text {soln }}=$ $-56 \mathrm{k} \mathrm{J} \mathrm{mol}^{-1}$ and the hydration energy is $-894 \mathrm{~kJ} \mathrm{~mol}^{-1}$ Estimate the lattice energy of the ionic compound.
The enthalpy of solution of an ionic compound can be calculated from the enthalpy of hydration of the individual ions and the lattice enthalpy. Use the information shown below: The enthalpy of solution of solid ammonium chloride: 705 kJ/mol The enthalpy of solution of solid ammonium nitrate: 646 kJ/mol Lattice energy of solid ammonium chloride: 307 kJ/mol Lattice energy of solid ammonium nitrate: -381 kJ/mol Enthalpy of hydration of the gaseous ammonium ion: -314 kJ/mol Enthalpy of hydration of the gaseous chloride ion: -381 kJ/mol Enthalpy of hydration of the gaseous nitrate ion: -314 kJ/mol
