The solution with a lower concentration of solutes is called a hypotonic solution.

Here's a breakdown:

* Hypotonic: This term describes a solution with a lower solute concentration compared to another solution. Water will move from the hypotonic solution to the hypertonic solution to try and equalize the concentrations.

* Hypertonic: This term describes a solution with a higher solute concentration compared to another solution.

* Isotonic: This term describes two solutions with the same solute concentration.
