The solubility of metal halides depends on their nature, lattice enthalpy and hydration enthalpy of the individual ions. Amongst fluorides of alkali metals, the lowest solubility of LiF in water is due to

Answer»

ionic nature of lithium fluoride
high lattice ENTHALPY
high hydration enthalpy for lithium ion
low IONZATION enthalpy of lithium atom

Solution :Due to smal size of `Li^(+)` and `F^(-)`lattice enthalphty in MUCH higher than hydration enthalpy
