When there is a very small amount of solute in solvent, the solution is considered dilute.

Here's a breakdown:

* Solute: The substance being dissolved.

* Solvent: The substance doing the dissolving.

* Solution: The uniform mixture of solute and solvent.

Dilute solutions have a low concentration of solute relative to the solvent. Think of it like adding a tiny pinch of salt to a large glass of water - you'd have a dilute salt solution.

Here are some other terms related to solute concentration:

* Concentrated solution: Has a high concentration of solute.

* Saturated solution: The maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.

* Unsaturated solution: Can still dissolve more solute.
