reaktiovälineinä
Reaktiovälineinä is Finnish terminology used to refer to the reagents that participate in a chemical reaction. In experimental descriptions, they denote substances that are consumed or transformed during the transformation, as opposed to solvents that mainly provide the reaction medium or to catalysts that facilitate the process without being consumed (though catalysts are still reagents in a broad sense). The term is commonly used in laboratory notebooks, articles, and method sections to distinguish the reagents from other reaction components and to document what was actually involved in the transformation.
Reaktiovälineinä can cover a range of chemical species, including oxidizing and reducing agents, acids and bases,
In practice, the phrase is used to introduce a list of substances in a procedure, for example:
