Answer:

There are two kinds of mixtures: heterogeneous and homogeneous. In heterogeneous mixtures, two or more ingredients (or phases, regions with uniform composition and properties) intermingle, but remain physically separate. Often it is possible to separate the original ingredients by physical means, such as filtering.

For example, an oil-and-vinegar salad dressing is a heterogeneous mixture—by allowing the “mixture to stand, and then carefully decanting the less dense oil layer from the more dense water layer,” the dressing’s original ingredients can be separated (Foundations of Chemistry, Mixtures, n.d., par. 1). Another example might be a mixture of sand and sugar, with its two solid phases. The difference between the sand and sugar grains can be detected by use of a magnifying glass, and the grains can be separated by pouring water over the mixture, thus washing the sugar out of the sand (Senese, 2010, par. 2).

Sometimes a microscope is required to detect that a mixture is actually heterogeneous: “Mayonnaise, for example, is an emulsion consisting of very fine droplets of oil and water” (Foundations of Chemistry, par. 2).

Heterogeneous mixtures can include mixtures consisting of two liquids, “a solid and a liquid, or a liquid and a gas, or even a gas and a solid.” Liquid/liquid mixtures are referred to as emulsions, solid/liquid mixtures are suspensions, gas/liquids are aerosols, and gas/solids are referred to as smoke

(Everything Science, Mixtures, n.d., par. 10).

Homogeneous mixtures are also called solutions, “a term that is most familiar when one of the components is a liquid.” In a homogeneous mixture, the constituent phases are indistinguishable, having merged into a single uniform phase, with its original parts undetectable even at very high magnification (Foundations, par. 3). A solution of salt, milk mixed into coffee, and metal alloys are all examples of this. “The air we breathe is another example of a homogeneous mixture since it is made up of different gases which are in a constant ratio, and which can't be visually distinguished from each other (i.e., you can't see the different components)” (Everything Science, par. 9). To describe such a mixture completely, “we need to give not only the identity of the components of which it is composed but also the relative amounts of the components,” since the ratio of the various components will be a factor in certain properties such as taste (the saltiness of a salt-and-water solution) or conductivity (the saltier a salt-and-water solution is, the greater will be its ability to conduct electricity) (Foundations, par. 5).

Components of homogeneous mixtures “can usually be separated by taking advantage of the different properties of the individual components.” In the process of distillation, a mixture may be heated “until the component that boils at the lowest temperature becomes a vapor and can be separated” (Foundations, par. 4).

Homogeneous mixtures are often greater than the sum of their parts: the alloy “[b]ronze, for example, is harder than either of the metals, copper and tin, from which it is composed, a property which led to the development of useful tools during the age that is named for it” (Foundations, par. 3).
