Updated on October 02, 2020 When you combine two or more materials, you form a mixture. In chemistry, a mixture is a combination that does not produce a chemical reaction. There are two categories of mixtures: homogeneous mixtures and heterogeneous mixtures. Here's a closer look at these types of mixtures and examples of mixtures. Key Takeaways: Mixture
Homogeneous mixtures appear uniform to the eye. They consist of a single phase, be it liquid, gas, or solid, no matter where you sample them or how closely you examine them. The chemical composition is the same for any sample of the mixture. Heterogeneous MixturesHeterogeneous mixtures are not uniform. If you take two samples from different parts of the mixture, they will not have an identical composition. You can use a mechanical method to separate components of a heterogeneous mixture (e.g., sorting candies in a bowl or filtering rocks to separate them from sand). Sometimes these mixtures are obvious, where you can see different types of materials in a sample. For example, if you have a salad, you can see different sizes and shapes and types of vegetables. In other cases, you need to look more closely to recognize this mixture. Any mixture that contains more than one phase of matter is a heterogeneous mixture. This can be tricky because a change of conditions can alter a mixture. For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture. Examples of Mixtures
Not a MixtureTechnically, if a chemical reaction is occurring when you mix two materials, it's not a mixture... at least not until it has finished reacting.
