How can mixtures be classified?
Mixtures can be broadly classified into two different categories, homogeneous mixtures and heterogeneous mixtures. Homogeneous mixtures are mixtures where the two components are indistinguishable from one another. They look like a single phase or medium. An example would be dissolving sodium choride in water. The mixture looks completely uniform and you cannot see the separate components. Heterogeneous mixtures are mixtures where the two components are distinguishable from one another. They do not form a single new phase or medium. An example would be adding iron filings to a cup of water. The iron simply sits in the bottom of the water and is clearly visible as separate from the water.
Mixtures can be classified in two types of mixtures, homogeneous and heterogeneous mixtures. Homogeneous mixtures have a uniform composition and heterogeneous mixtures have a nonuniform composition.
