Vedclass · Answer

(C) $1$. Water of crystallisation is the fixed number of water molecules present in one formula unit of a salt.$2$. Small, highly charged cations like $Li^+$, $Mg^{2+}$, and $Be^{2+}$ have high hydration energy and tend to form hydrated salts (e.g., $LiCl \cdot H_2O$, $MgCl_2 \cdot 6H_2O$, $BeCl_2 \cdot 4H_2O$).$3$. $Cs^+$ is a large cation with low charge density, resulting in low hydration energy. Therefore, $CsCl$ crystallises as an anhydrous salt.$4$. Thus, $CsCl$ does not contain water of crystallisation.
