Is An Alloy A Heterogeneous Mixture. Examples of homogeneous mixtures are air, saltwater, most alloys (like brass or steel), and vinegar (acetic acid and water). An alloy may be a solid solution of metal elements (a homogeneous mixture) or a mixture of metallic phases (a heterogeneous mixture of two or more solutions).

Alloys can be further classified as homogeneous (consisting of a single phase), heterogeneous (consisting of two or more phases), or intermetallic (where there is no distinct boundary between phases). Complete step by step answer: An alloy is a heterogeneous mixture of metals.
