A homogeneous compound is a compound in which individual components are uniformly mixed throughout the compound. Homogeneous compounds are consistent in their composition and are only present in one state of matter at a time. An example of a homogeneous compound would be a metal alloy, such as steel.
Homogeneous compounds can be either liquid, solid or gas and are also known as homogeneous mixtures. Because of their uniform nature, the individual components in a homogeneous compound are not distinguishable by sight and are not easily separated by mechanical means. They can be separated through advanced methods, however, such as through the use of a centrifuge.
Homogeneous compounds are a type of mixture, meaning that they are comprised of more than one component, which may be an element, ion or molecule. The other type of mixture is a heterogeneous compound, in which individual components are found in uneven amounts, can be visibly distinguished and are not as difficult to separate mechanically. Heterogeneous mixtures can also be found in different states of matter.
If a compound has a fixed ratio of components and doesn't have any variances, such as the presence different elements or impurities, it is referred to as a pure compound. Mixtures can be formed by combining several pure substances, and they sometimes yield pure substances when separated into individual components.
