The three general types of mixtures in chemistry are solutions, suspensions and colloids. All mixtures contain at least two different substances and can be liquids, gases or solids.Continue Reading
Solutions are the simplest mixture, consisting of two substances that interact and have reasonably small particle sizes. A solution has a solvent and at least one solute, depending on how many substances are being mixed together. If any of the substances changes phase while making the solution, it is considered a solute. If there are no phase change between two or more substances, the substance that there is the most of is considered the solvent, while all the rest are solutes.
A suspension is a mixture where components must be forced to distribute evenly. In time, if left to rest, the components will separate into layers. A common example of this is oil and water, which needs to be shaken to ensure a temporarily uniform solution.
Colloids are mixtures where substances are evenly distributed, but not fully dissolved due to a large particle size. The substances with the largest particles can be filtered out through a membrane. To test for a colloid, a light is shone through the mixture. The light will simply shine through a true solution, but be clearly visible when shone on a colloid mixture.Learn more about Solutions & Mixtures
There are three types of solutions in chemistry: gaseous solutions, liquid solutions, and solid solutions. These are equivalent to the three main phases used in chemistry.Full Answer >
Beach sand, air with clouds, oil and vinegar, granite and pizza are five examples of heterogeneous mixtures. This is because they all have components that stay separated when put together.Full Answer >
According to Ducksters, variable methods of separating mixtures exist, such as filtration, distillation and centrifuge. Other methods include chromatography, sublimation and crystallization. Separating mixtures is useful for isolating or extracting a particular substance from another.Full Answer >
Compounds and mixtures differ primarily in two ways: Compounds have a constant composition, whereas mixtures do not, and mixtures can be separated easily, while compounds can only be separated by destroying the compound.Full Answer >
