Question

Quizplus · Accepted Answer

KI (potassium iodide) is an ionic compound, and its solubility in nonpolar solvents is poor because the ionic (solute-solute) interactions within KI are much stronger than the interactions it can form with nonpolar solvent molecules (solute-solvent interactions) or the interactions among the solvent molecules themselves (solvent-solvent interactions). Nonpolar solvents cannot effectively overcome the strong ionic bonds in KI to dissolve it.
