When a solute is fully dissolved in water and no more solute can be dissolved at that temperature, the solution is said to be

  1. Saturated ✓
  2. Unsaturated
  3. Dilute
  4. Concentrated

Explanation

A saturated solution contains the maximum amount of dissolved solute possible at a given temperature. Adding more solute will not dissolve it; the excess settles to the bottom.

At saturation point, the rate of dissolving equals the rate of crystallization. A dynamic equilibrium exists where particles dissolve and crystallize at equal rates.

Unsaturated solutions can still dissolve more solute. Supersaturated solutions temporarily hold more than normal, but they are unstable and crystallize easily when disturbed.
