Which of the following describes a solution that is only partially soluble?

The concept of partial solubility relates to the ability of a solute to mix with a solvent to a limited extent. A solution that is only partially soluble means that the solute does not completely dissolve in the solvent, resulting in a mixture where both phases can coexist.

The term "partially miscible" specifically describes substances that can mix with each other in limited amounts. This means that while some solute can dissolve in the solvent, there will still be some undissolved solute present in the solution due to the solute’s limited solubility in that particular solvent. For example, certain organic solvents may mix with water only up to a certain point, and any excess would remain separate instead of fully dissolving.

On the other hand, terms like concentrated or dilute refer to the amount of solute in a solution relative to the solvent, but they do not specify anything about solubility limits. An unsaturated solution means that more solute can still dissolve in the solvent, which can also create confusion regarding partial solubility since it implies that the solute is fully dissolvable to some extent.

Therefore, "partially miscible" is the most accurate term to describe a solution that exhibits limited solubility,
