A homogeneous mixture of two or more pure substances is called a solution.

Here's why:

* Homogeneous: Means the mixture has a uniform composition throughout. You can't see individual components.

* Solution: A specific term for a homogeneous mixture, usually involving a solid, liquid, or gas dissolved in a liquid.

Examples of solutions:

* Saltwater (salt dissolved in water)

* Air (gases like nitrogen and oxygen dissolved in each other)

* Sugar dissolved in coffee
