WebJun 7, 2024 · The lattice energy depends on the sum of the anion and cation radii (r + + r - ), whereas the hydration energy has separate anion and cation terms. 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 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. WebAs these bonds form to produce a lattice structure, more energy is released compared to from ions with a lower charge. This results in a more exothermic (more negative) lattice enthalpy. Conversely, as ionic radius increases, charge density decreases, resulting in weaker bonds during the formation of a lattice so the overall enthalpy change is ... central ac size by square footage

WebMay 29, 2024 · For the lattice energy, both cation and anion radii release more potential energy, when they are smaller. It is similar as if a satellite goes to the lower orbit, or an electron in an atom goes to the quantum state with lower energy. For multiatom anions, it is more complicated due their structure and charge distribution.

WebWhen, however, an ionic compound such as sodium chloride (NaCl) dissolves in water, the sodium chloride lattice dissociates into separate ions which are solvated (wrapped) with a coating of water molecules. Nonetheless, NaCl is said to dissolve in water, because evaporation of the solvent returns crystalline NaCl. 1 comment ( 5 votes) Upvote
