Among halides of alkaline earth metals fluorides are less soluble, but `BeF_(2)` is more soluble. Why? 

Text Solution

Verified by Experts

Lattice energies of ionic flurides are high .
Hence , florides of alkaline earth metals are less soluble .
`BeF_(2)` is covalent and has the tendency to form hydorgen bonding with water .
`BeF_(2)` is more soluble in water due to high hydration energy of `Be^(2+)` ion .

The solubility of sulphates of alkaline earth metals in water shows the order

BeO and Be(OH)_(2) are amphoteric while the oxides and hydroxides of other alkaline earth metals are basic. The solubility of hydroxides increases as we move down the group from Be to Ba but the solubility of sulphates and carbonates decreases in that order the thermal stability of carbonates and sulphates of alkaline earth metals increases from Be to Ba as we move from top to bottom in the group. The solubility in water of sulphates down the Be group is Be gt Mg gt Ca gt Sr gt Ba this is due to
