← ScienceWhich outcome follows introduction of deionized water to lead(II) iodide?
A)Precipitate forms due common-ion effect
B)Increased solubility through ion hydration✓
C)Decreased solubility through lattice disruption
D)A protective oxide inhibits dissolution
💡 Explanation
Increased solubility results because ion hydration weakens ionic bonds via dipolar attraction between water and ions, resulting in increased ion mobility and dissolution rather than precipitation. Common-ion effect needs specific ions, not deionized water, therefore it is not A.
