The term descriptive of the solution with a higher solute concentration is hypertonic.

Here's a breakdown:

* Hypertonic: A solution with a higher solute concentration compared to another solution.

* Hypotonic: A solution with a lower solute concentration compared to another solution.

* Isotonic: Two solutions with equal solute concentrations.

The terms are relative, meaning that one solution is hypertonic to another only in comparison.
