In chemistry, a substance containing two or more elements or compounds that still retain their separate physical and chemical properties. There is no chemical bonding between them and they can be separated from each other by physical means (compare
compound).
The
separation of mixtures can be achieved by a number of methods, such as
filtration and distillation. Examples of mixtures include rocks, air, crude oil (unrefined petroleum), all solutions (such as sea water), and all metal alloys (such as steel).
