A heterogeneous mixture Is a mixture which is composed of elements that are nonuniform or have localized regions having different properties In physical chemistry and materials science, the definition of a heterogeneous mixture is that of a mixture containing components in distinct phases Thus, a combination of salt and steel wool is a heterogeneous mixture because it is easy to see which particles of the matter are salt crystals and which are steel wool On the other hand, if you take salt crystals and dissolve them in water, it is very difficult to tell that you have more than one substance present just by looking—even if you use a powerful microscopeA mixture is composed of two or more types of matter that can be present in varying amounts and can be separated by physical changes, such as evaporation (you will learn more about this later) A mixture with a composition that varies from point to point is called a heterogeneous mixture Homogenous And Heterogenous Mixtures Chemistry For ...
