Solubility of an ionic compound in water is mainly dependent on:
a.Lattice enthalpy , b. Hydration enthalphy
Both these factors oppose each other and the resultant of these determines the solubility of an ionic compound in water. If lattce enthalpy has greater value, the compound is less soluble.
In case hydration enthalpy has greater value, the compound is highly soluble in water.
`BeF_(2)` is soluble in water while fluorides of other alkaline earth metals are insoluble because of:
A. Covalent nature of `BeF_(2)`
B. Ionic nature of `BeF_(4)`
C. Greater hydration enthalpy of `Be^(2+)`ion
D. Greater lattice enthalpy of `Be^(2+)` ion
