A solution that will continue to dissolve more solute.

A solution that will continue to dissolve more solute.

• A. Colloid
• B. Concentrated Solution
• C. Unsaturated solution
• D. Saturated solution

Answer: (C)

The main idea is solubility and how full the solution is at the current conditions. An unsaturated solution has not yet reached the maximum amount of solute that can dissolve at that temperature, so it can still dissolve more solute. As you add and dissolve more, it will continue until you hit the solubility limit. In contrast, a saturated solution is already at that limit at the given temperature, so extra solute won’t dissolve and will remain undissolved. A concentrated solution describes how much solute is present relative to solvent, but doesn’t by itself say whether more can dissolve. A colloid is a mixture with dispersed particles, not a true dissolved solute, so it isn’t about dissolving more solute in the same sense.
