The compound with more than 10% solubility in pure water is:
Correct answer: C. K2πΆπ3
- A. MππΆπ3
- B. Aπ2(πΆπ3)3
- C. K2πΆπ3
- D. πππΆπ3
Explanation
The solubility of compounds in pure water depends upon their respective lattice energy. If lattice energy is larger than the hydration energy i.e. ions are strongly held and the solubility of that compound in water is less. And if lattice energy is less than the hydration energy then the compound is dissociated into ions and hence solubility increases. Lattice energy is directly related to charge density (charge/size).
