Alkali metal salts are water soluble and ionic in nature. Two factors such as lattice energy and hydration energy decide the extent of solubility. These two factors are opposing in nature solubility will be high if hydration energy is high. Higher will be the extent of hydration if size of the ion is smaller. Hydration of ions is exothermic process.Hydration energy also plays a role in deciding reducing power of alkali metals in solution. Among the following the least soluble is
