Vedclass · Accepted Answer

$LiF$

Vedclass · Answer

(A) The enthalpy of solution $(\Delta H_{sol})$ is the sum of lattice energy $(\Delta H_{lattice})$ and hydration energy $(\Delta H_{hyd})$. For $LiF$,the lattice energy is very high due to the small size of both $Li^+$ and $F^-$ ions. Since the lattice energy is significantly higher than the hydration energy,the overall enthalpy of solution for $LiF$ is positive,making it sparingly soluble in water at room temperature.
