The size of the lattice energy is connected to many other physical properties including solubility, …
WebJun 7, 2024 · Generally the solvation of small ions (typically cations) dominates the hydration energy because of the 1/r 2 dependence. (9.12.1) E L α 1 r + + r −. (9.12.2) E H α 1 r + 2 + 1 r − 2. For salts that contain large anions, E L doesn't change much as r + changes. That is because the anion dominates the r + + r - term in the denominator of ... WebJan 15, 2024 · In one definition, the lattice energy is the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. This definition causes the value for the lattice energy to always be positive, since this will always be an endothermic reaction. The other definition says that lattice energy is the reverse process ...
