Key Concepts

Heterogeneous Mixture

A heterogeneous mixture is a mixture in which the individual components can be seen as separate phases. The composition varies from one part of the mixture to another, often making it easy to identify and physically separate the different substances that form the overall mixture.

Pure Substance

A pure substance is a material that has a constant composition and distinct properties, consisting of a single type of element or compound. This means that no matter how much of the substance is collected, its composition remains consistent throughout, and it cannot be separated into different components by simple physical means.

Mixture

A mixture is a combination of two or more substances that are physically intermingled but not chemically bonded. The components maintain their own properties and can usually be separated by physical processes, such as filtration or evaporation, making mixtures variable in composition.

Homogeneous Mixture

A homogeneous mixture is a type of mixture where the components are uniformly distributed and indistinguishable from one another at the macroscopic level. The composition is consistent throughout, resulting in a single-phase system that appears as a uniform substance.
