Maximum solubility of hydroxide in water:
The solubility of a hydroxide compound in water depends on the lattice enthalpy and hydration energy of the cations present in the compound.
Lattice enthalpy:
Lattice enthalpy is the energy required to break the ionic bonds in a solid crystal lattice and convert it into individual gaseous ions. It is directly proportional to the charge and inversely proportional to the size of the ions. Smaller ions have higher lattice enthalpy.
Hydration energy:
Hydration energy is the energy released when gaseous ions are surrounded by water molecules and form hydrated ions. It is directly proportional to the charge and inversely proportional to the size of the ions. Smaller ions have higher hydration energy.
Solubility of hydroxides:
The solubility of hydroxides depends on the balance between lattice enthalpy and hydration energy. Hydroxides of alkaline earth metals (Group 2 elements) are extensively hydrated due to their high hydration energy. This hydration energy compensates for their high lattice enthalpy, allowing for greater solubility in water compared to hydroxides of other elements.
Answer:
Among the given options, barium hydroxide (Ba(OH)2) has the maximum solubility in water because it is an alkaline earth metal hydroxide and is extensively hydrated. The smaller size of the Ba2+ cation compared to other alkaline earth metals leads to higher lattice enthalpy, but its high hydration energy compensates for it, resulting in greater solubility in water.
In contrast, magnesium hydroxide (Mg(OH)2) has lower solubility due to its larger size, resulting in lower lattice enthalpy and hydration energy compared to barium hydroxide. Calcium hydroxide (Ca(OH)2) also has lower solubility compared to barium hydroxide because of its larger size and lower hydration energy. Beryllium hydroxide (Be(OH)2) has the lowest solubility among the options due to its small size and high lattice enthalpy, which is not sufficiently compensated by its hydration energy.
Therefore, the correct answer is option 'A', Ba(OH)2, which has the maximum solubility in water among the given hydroxides.
