A mixture in which substances are evenly distributed throughout the mixture.

A homogeneous mixture is made of two or more substances that are evenly distributed so you can’t see distinct parts. Every sample taken from such a mix has the same composition and properties, which is what “evenly distributed throughout” describes. A common example is salt dissolved in water—the salt grains are spread uniformly, so the solution looks the same everywhere. This differs from a heterogeneous mixture, where the different substances remain in separate parts and can often be seen as different regions or phases, like oil floating on water or a mixture with visible chunks. A pure substance, on the other hand, is just one kind of matter with a fixed composition (like a single element or a single compound), not a blend of different substances.
