WebOct 6, 2024 · The plastic strip holds twenty mini-test chambers containing dehydrated media having chemically defined compositions for each test. A bacterial suspension is used to rehydrate each of the wells. After incubation, some of the wells will have color changes due to pH differences: others produce end products that must be identified with reagents. In chemistry, a reagent or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction mechanism, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so they are not reactants. In biochemistry, e…

WebIn one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction. In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate.
