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 solubilitty of LiF in water is due to metals, the lowest solubility of LiF in water is due to
A
Ionic nature of lithium flouride
B
High lattice enthalpy
C
High hydration ethalpy of lithium ion
D
Low ionisation enthalpy of lithium atom
Text Solution
Verified by Experts
The correct Answer is:
B
Due to strong packing of `Li^(+) and F^(-)` ion, lattice energy of LiF is higher than its hydration energy.

The solubility order for alkali metal fluoride in water is :
A white metal sulphide soluble in water is
Which of the following alkali metal halides has the lowest lattice energy
Alkali metal salts ionic and soluble in water. The solubility of an ionic compound depends on (i) lattic ethalpy and (ii) hydration enthalpy. These two factor oppose each other. If hydration ethalpy is high, the ions will have greater tendency to be hydrated and therefore the solubility will be high. The smaller the cation, the greater is the degree of hydration. The reducing behaviour of alkali metals in solution is also dependent on the hydration enthalpy besides other factors. The radius of which of the hydrated ion is the highest ?
