Schwefelfüggvény
Schwefelfüggvény is a term originating from German, literally translating to "sulfur function." In its most common context, it refers to a concept within older, non-standard chemical nomenclature. Historically, it was used to describe the state of sulfur within a compound, particularly in terms of its oxidation state or its role as a component. For instance, it might have been employed to indicate whether sulfur was acting as an acid, a base, or a neutral element in a particular molecular structure.
The term is not widely used in modern IUPAC (International Union of Pure and Applied Chemistry) nomenclature.
