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

Options

  1. AIonic nature of lithium fluoride
  2. BHigh lattice enthalpy
  3. CHigh hydration enthalpy of lithium ion
  4. DLow ionisation enthalpy of lithium atom

Correct answer

B. High lattice enthalpy

Step-by-step solution

The lowest solubility of LiF in water is due to strong packing of Li+{Li}^{+} and F−F^{-} ion, lattice energy of LIF is higher than its hydration energy.
