WebLattice enthalpy is a measure of the strength of the forces between the ions in an ionic solid. The greater the lattice enthalpy, the stronger the forces. Those forces are only completely broken when the ions are present as gaseous ions, scattered so far apart that there is negligible attraction between them. WebJan 24, 2024 · To measure the enthalpy of solution experimentally, we can use a solution calorimeter to measure a temperature change of a known mass: q = mass * specific heat * Δ T. where: mass = total mass of the …
