Pure substance is a chemical description of a substance or matter containing only one element, literally a 'pure substance'. The importance of this definition is that it refers to a specific set of characteristics and known chemical and physical properties. A variation on this definition is sometimes used in cases where there's more than one element present, but the requirement for known properties is met by the compound. |
Examples of Pure Substance:
Copper carbonate: referred to as a pure substance because of the common composition of all forms of the material. Gold: It's a naturally non-allotropic material, homogeneous in composition. https://en.wikipedia.org/wiki/Basic_copper_carbonate https://en.wikipedia.org/wiki/Chemical_substance https://van.physics.illinois.edu/qa/listing.php?id=469 https://campus.dyc.edu/cpc022/day1/pure.spm https://ari.cankaya.edu.tr/~ebiber/ie211/Pure%20Substance.pdf |
