    But in case of RbI , Rb(5s)-I(5p) overlap takes place,so it has more lattice enthalpy,thus the order should be LiI>NaI>KI>CsI>RbI🙄

    Difference between hydration energy and lattice energy?

    eduncle-logo-app

    lattice energy is the amount of energy that is required when 1 mole of ionic crystal break into ions. and Hydration energy is the amount of energy that is released when ionic crystal dissolve into water

    In case of compounds containing large anions like I-, the solubility will decrease with increase of cationic size. Solubility of alkali metal iodides decrease in the following order : LiI > NaI > KI > RbI > CsI
