In case of compounds containing large anions like I-, the solubility will decrease with increase of cationic size.
In case alkaline earth metals, the decrease in solvation energy is more rapid than the decrease in lattice energy with the increase in the size of cation.
Solubility of alkali metal iodides decrease in the following order :
LiI > NaI > KI > RbI > CsI
