Experiment to calculate a lattice enthalpy of Ammonium Nitrate by measuring its Solution Enthalpy, and then using an enethalpy cycle with Hydration Enthalpies to calculate the Lattice Enthalpy Indirectly.

Students are guided through the practical procedure and the resulting calculation.

Students are encouraged to think about why the melting point of the salt is anomalously low, (due to the large size of its constitutent ions).
