Air, syrup and rain are examples of homogenous substances, while pizza, blood and gravel are examples of heterogeneous ones. The components of homogenous substances are uniformly distributed in a single phase, while those of heterogeneous substances are non-uniformly distributed and may be comprised of several phases.Continue Reading
The distinction between homogeneous and heterogeneous substances is important in the classification of chemical mixtures. It is usually possible to separate a heterogeneous substance into its individual components through physical means, such as sieving, filtration or centrifugal separation.
The separation of heterogeneous substances is usually much more difficult, needing distillation, recrystallization or another complex physiochemical processes. Some heterogeneous mixtures can be made homogeneous through a process called homogenization. This process is commonly used to mix milk with cream, a heterogeneous mixture, to yield homogenized milk.
The concepts of homogeneity and heterogeneity can be applied in other branches of science besides chemistry. Homogeneity and heterogeneity can be applied to the structure of galaxies in astronomy, for example. Galaxies with uniform distributions of stars are homogeneous, while those with non-uniform distributions are heterogeneous. In physics, systems with multiple phases of the same type of matter, such as ice, liquid water and water vapor, are called heterogeneous systems.Learn more about Solutions & Mixtures
Air is an example of a gas-gas solution, or a solution in which a gaseous solute is dissolved in a gaseous solvent. Air is comprised of multiple gases.Full Answer >
You can compare and contrast mixtures and pure substances by determining if the substance can be separated into homogeneous materials. Determine if the substance can be changed into a different substance as well.Full Answer >
A mixture is the result of combining two or more substances that do not react chemically. In order for a solution or combination to be labelled as a mixture, it must be possible to separate the individual components through physical means, without resorting to chemical reactions.Full Answer >
In scientific language, a solution is a mixture of at least two substances in which the particles of the substances are of atomic or molecular size. A solution is a homogeneous mixture, which means that all parts of the mixture are exactly the same as every other part.Full Answer >
