which of the following questions has a positive enthalpy of solution?
Licl
LiBr
LiI
LiF

1. By positive enthalpy of solution we mean that the process of solvation is endothermic in nature.
2. Li+​ being small in size has a large enthalpy of solution,thus exothermic process.
3. But in LiF,the lattice energy is very high when compared to hydration energy,thus it has Positive enthalpy of solution.
