Which one of the following is more soluble in water?
Correct answer: D. Ba(OH)2
- A. Be(OH)2
- B. Ca(OH)2
- C. Mg(OH)2
- D. Ba(OH)2
Explanation
Group II metal hydroxides become more soluble in water as you go down the column(group). This trend can be explained by the decrease in the lattice energy of the hydroxide salt and by the increase in the coordination number of the metal ion as you go down the column.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
