A solution is a combination of different materials such that the mixture is evenly distributed. This means that one material dissolves evenly into the other, creating a homogeneous product. For example, sugar dissolves into water, creating a solution; meanwhile, sand does not dissolve in water, but instead settles to the bottom, so it does not create a solution.
Solutions can consist of different types of materials, including liquids, solids and gases. Metal alloys are a type of solid solution made by combining different types of metal to create a third, novel material. When one material is able to create a solution with another, it is called a "solvent" material.Learn More
Chromatography is used by scientists to separate, analyze and identify the individual parts of a mixture. For example, chromatography was used to create synthetic insulin and to understand how the sun's energy is used by plants to make food.Full Answer >
Distillation works by heating a mixture until a substance boils off, which can then be collected in another container after condensing. Distillation is only effective if the substances in the original mixture have significantly different boiling points, so that all of one substance can be boiled off before the other(s) start to turn to gas as well.Full Answer >
Fog is a mixture because it is an aerosol of water droplets or ice crystals in air. Fog can also contain molecules of acids or ammonia.Full Answer >
Milk is not a pure substance; it is considered a mixture because it does not occur naturally on its own. It is a mixture that combines mostly water, sugar, fat and proteins.Full Answer >
