Purity Defines a Substance’s Chemical Identity?
The chemical identity of any substance is fundamentally defined by a specific, unique set of properties, both physical and chemical. These characteristic properties, such as melting point, boiling point, density, and reactivity, are intrinsic to a substance comprised of a single type of particle, like an element or compound. The concept of purity is therefore absolute and central to chemistry, a pure substance consists of only one kind…
