A mixture is a material composed of two or more substances that are physically combined but not chemically bonded, meaning each component retains its characteristic properties. In a mixture, the components can be separated from one another using physical methods, such as filtration, distillation, or magnetism, without involving a chemical reaction. The composition of a mixture is often described by the relative proportions of its constituent elements or compounds. Scientifically analyzing a mixture involves determining the identity and percentage weight of each component, which helps understand the overall properties, such as density or conductivity, of the combined substance.
