We can predict whether or not a solute dissolves in a solvent with the rule "like dissolves like." This rule means that
A) a solute with the same diameter as the solvent will dissolve.
B) a solute with the same phase as the solvent will dissolve.
C) a solvent with the same polarity as the solvent will dissolve.
D) a solute with the same mass as the solvent will dissolve.
E) a solute contains some of the same elements as the solvent it will dissolve.

Question

Quizplus · Accepted Answer

"Like dissolves like" means that a solute with the same polarity as the solvent will dissolve. Polarity refers to the distribution of charges in a molecule. Polar molecules will dissolve in polar solvents, and nonpolar molecules will dissolve in nonpolar solvents. The other choices are incorrect because they do not take into account the polarity of the molecules.
