In physical chemistry and materials science, the definition of a heterogeneous mixture is somewhat different. Here, a homogeneous mixture is one in which all components are in a single phase, while a heterogeneous mixture contains components in different phases.
In chemistry, the word is most often applied to a heterogeneous mixture. This is one which has a non-uniform composition. A mixture of sand and water is heterogenous. Concrete is heterogeneous. In contrast, a homogeneous mixture has a uniform composition. An example is a mixture of sugar dissolved in water.
Definition of Heterogeneous Mixtures. A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties. In some mixtures, the initial ...
Homogeneous vs. Heterogeneous Mixtures. Mixtures can be either heterogeneous or homogeneous. Unlike a heterogeneous mixture, a homogeneous mixture is a mixture that is uniform throughout; this means that the different components of the mixture cannot be distinguished from one another in some way.

Imagine you’re sitting in a high school biology class or a college chemistry lab. The professor is giving a heated lecture using a whole host of long, difficult words. But every time she says “heterogeneous mixture” or “Heisenberg’s Uncertainty Principle” she spells out the entire term one letter at a time.
Physics and chemistry. A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds).Examples are: mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a portion salad, trail mix, and concrete (not cement).A mixture of powdered silver metal and powdered gold metal would represent a heterogeneous mixture of two elements.
A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components whose proportions vary throughout the sample."Homogeneous" and "heterogeneous" are not absolute terms but depend on context and the size of the sample. In chemistry, a homogeneous suspension ...
A puddle of mud counts as a heterogeneous mixture - dirt, leaves, grasses, animal byproducts - all blended together in water. Pizza is a heterogeneous mixture of dough, sauce, cheese, and other toppings. A bowl of oatmeal with raisins is a heterogeneous mixture.
The scientific definition of a mixture is more complicated than the definition you use in everyday life. The degree of combination, the presence or lack of chemical reactions, the size of the particles and the distribution of one substance among another all determine whether something fits the scientific characterization of a mixture and what type of mixture it is.
