$LiClO_4$

Vedclass · Answer

(D) The solubility of alkali metal perchlorates $(MClO_4)$ in water decreases as the size of the cation increases. This is because the lattice energy of these salts decreases less rapidly than their hydration energy as the cation size increases. Since $Li^+$ has the smallest ionic radius among the alkali metals,it has the highest hydration energy. Therefore,$LiClO_4$ is the most soluble in water among the given options.
