For example Hydrochloric Acid is the chemical reagent that would cause Calcium Carbonate to release Carbon Dioxide . Similarly, but less obviously, hydrochloric acid is the chemical reagent that reacts with Zinc to produce Hydrogen , even though in this case the hydrogen comes from the acid and not the metal. To classify any of the chemicals involved in a chemical reaction as the "reagent" is thus largely a matter of convention or perspective, and commonly most non- Solvent s involved in a reaction are referred to as reagents. In another use of the term, when purchasing or preparing chemicals, "reagent-grade" describes Chemical Substance s of sufficient Purity for use in Chemical Analysis , Chemical Reaction s or physical testing. Purity Standards for reagents are set by organizations such as ASTM International . For instance, reagent-quality Water must have very low levels of impurities like Sodium and Chloride Ions , Silica , and Bacteria , as well as a very high Electrical Resistivity . SEE ALSO |
