The solubility of an ionic compound depends upon lattice energy and hydration energy of that compound. Lattice energy involves the fact that how tightly are ions held together in ionic lattice whereas hydration energy involves the attraction of ions towards water molecule to get themselves hydrated. The dissolution occurs when hydration energy predominates over lattice energy. The solubility also depends upon this difference. More is more is solubility.
Select the incorrect choice :
Options:
Answer:
Solution:
The solubility of alkaline earth metal oxalates generally decreases down the group due to decreasing hydration energy outweighing the decreasing lattice energy. Therefore, option C is incorrect.
A. Solubility of carbonates, sulfates, and nitrates decreases from Be to Ba. This is correct.
B. Solubility of alkaline earth metal hydroxides is less than alkali metal hydroxides in a period. This is correct.
D. on passing in lime water turns it milky. This is correct.
