Which example correctly shows the idea that substances of similar nature dissolve better?
Answer and explanation
Correct answer: A non-polar substance dissolving in a non-polar solvent
The phrase “like dissolves like” means that substances with comparable polarity and intermolecular forces tend to mix more readily. Thus a non-polar solute is generally more soluble in a non-polar solvent. Sand does not dissolve completely in water, oil and water are largely immiscible, and wood does not simply form ions in water. These alternatives do not demonstrate the principle.
