What is a homogeneous mixture composed of two or more substances called?

A homogeneous mixture composed of two or more substances is referred to as a solution. In a solution, the different components are mixed at the molecular level, resulting in a uniform composition throughout the mixture. This means that the solute (the substance being dissolved) is completely integrated into the solvent (the substance doing the dissolving), making it impossible to distinguish the individual parts with the naked eye.

For example, when salt is dissolved in water, it forms a solution in which the salt particles are evenly distributed in the water, and the resulting mixture is transparent. Solutions can be in various phases, including solid, liquid, and gas, but they maintain the characteristic of homogeneity.

In contrast, a compound refers to a substance formed when two or more elements are chemically bonded together, which results in a material with its own distinct properties that are different from the original elements. An element is a pure substance that cannot be broken down into simpler substances by chemical means. An alloy is a specific type of mixture where two or more metals (or a metal and non-metal) are combined, often to enhance properties like strength or corrosion resistance, but it does not qualify as a homogeneous mixture in the same context as a solution.
