B)a small magnitude of the lattice energy of the solute
C)a large polarity of the solvent
D)all of the above
E)none of the above

Quizplus · Accepted Answer

A large magnitude of the solvation energy of the ions favors the solubility of an ionic solid in a liquid solvent because it indicates that the solvent molecules can effectively surround the ions and stabilize them in solution. A small magnitude of the lattice energy of the solute also favors solubility because it suggests that the crystal lattice of the solid can easily be broken apart, releasing the ions into solution. A large polarity of the solvent also favors solubility because it allows for effective solvation of the charged ions. Therefore, all of the above factors favor solubility of an ionic solid in a liquid solvent.
