Answer 1

Explanation:

Order of solubility: MgF₂ < CaF₂ < SrF₂ < BeF₂

BeF₂ has highest solubility as Be+² have high hydration energy

Answer 2

Answer:

Down the group the ionic character increase

Explanation:

more ionic character means metal dissociates into ions and easily combine with water molecules

Hence,the solubility order

BaF2>SrF2>CaF2>MgF2>BeF2
