Solubility in water is related to the ionic nature and size. Click here 👆 to get an answer to your question ️ What is the solubility order of alkali metal flouride in water? All alkali metal salts are ionic (except Lithium) and soluble in water due to the fact that cations get hydrated by water molecules. Q9. The degree of hydration depends upon the size of the cation. Since hydration energy is inversely proportional to radius of ion, I would expect Lithium to release the largest hydration energy and thus be the most soluble.
