Why is LiF almost insoluble in water, whereas LiCl soluble not only in water but also in  acetone?

Text Solution

Verified by Experts

The low solubility of Lif in water is due to its very high lattice enthalpy `(F^(-))`ion is very small in size)). On the other hand, in lithium chloride (Lici) the lattice enthalpy is comparatively very small. This means that the magnitude of hydration enthalpy is quite large. Therefore lithium chloride dissolves in water. It is also soluble in acetone due to dipolar attraction (Acetone is polar in nature)
