* Solution: A solution is a homogeneous mixture where one substance (the solute) is dissolved completely into another substance (the solvent). The resulting mixture has a uniform composition throughout.

* Mixture: A mixture is a combination of two or more substances where each substance retains its own chemical identity.

In Sprite:

* Solute: The primary solute is sugar (and possibly other sweeteners), along with flavorings and citric acid.

* Solvent: The solvent is water.

The sugar, flavorings, and citric acid dissolve completely into the water, creating a homogeneous mixture where you cannot see the individual components. Therefore, Sprite is a solution.
