The solubility rule "like dissolves like" is not adequate for predicting solubilities when the solute is a(n)
A) nonpolar gas
B) ionic compound
C) nonpolar liquid
D) polar gas

Question

Quizplus · Accepted Answer

The solubility rule "like dissolves like" mainly applies to the solubility of substances based on their polarity. However, when the solute is an ionic compound, its solubility in a solvent depends not only on the polarity of the solvent but also on the specific interactions between the ions of the solute and the molecules of the solvent. Ionic compounds often dissolve in polar solvents like water due to ion-dipole interactions, which are not adequately explained by the simple concept of "like dissolves like."
