PURE SUBSTANCE A pure substance is a type
PURE SUBSTANCE A pure substance is a type of matter with a fixed makeup of atoms. Elements are always a pure substance. H 2 O and Na. Cl, is a pure substance, it is always the same. But NOT when mixed together in a solution! Substances can be either elements or compounds.
