Be(OH)₂ has the lowest Kₛₚ at room temperature.
Explanation:
- The Kₛₚ is dependent on the solubility of a compound in water.
- As the solubility of a substance increase at a particular temperature, the Kₛₚ of that substance increase.
- The options show us the four hydroxides of group 2 elements.
- Among a group, we know that the size of the atoms increase while going down the table.
- So Beryllium have the smallest size among all of them.
- This results in the tightest bonds with hydroxide radicals because the smaller the central atom, the tighter is the bond.
- So tighter bond has higher bond energies.
- So beryllium hydroxide needs highest energy to break Be - OH bonds, hence lowest solubility.
