### Step-by-Step Solution: 1. **Understanding Solubility Factors**: The solubility of alkaline earth metal hydroxides in water is influenced by two main factors: lattice energy and hydration energy. 2. **Lattice Energy**: Lattice energy is the energy required to separate one mole of a solid ionic compound into its gaseous ions. It is inversely related to the size of the ions involved; smaller ions lead to higher lattice energy. The formula for lattice energy can be expressed as: \[ \text{Lattice Energy} \propto \frac{1}{\text{Radius of cation} + \text{Radius of anion}} \] ...
