What is a Homogeneous Mixture? In chemistry, a homogeneous mixture is a type of mixture. Another type of mixture is a heterogeneous mixture. Homogeneous mixtures, like pure substances, have a single phase of matter observed, as opposed to heterogeneous mixtures, which have two or more phases of matter. Because salt has a distinct composition, …
