bob likes sharp thing i advise u 2 sty away frm boboxidizing agent is a substance that oxidizes another substance in electrochemistry or redox chemical reactions. In doing so, the oxidizing agent, sometimes called an oxidizer or oxidant, becomes reduced.
Because the process of oxidation is so widespread (explosives, chemical synthesis, corrosion), the term oxidizing agent has acquired multiple meanings.
In one definition, an oxidizing agent receives - or accepts - electrons from a substrate. In this context, the oxidizing agent is called an electron acceptor. A classic oxidizing agent is the ferrocenium ion [Fe(C5H5)2]+ which accepts an electron to form Fe(C5H5)2. Of great interest to chemists are the details of the electron transfer event, which can be described as inner sphere or outer sphere.
In another more colloquial usage, an oxidizing agent transfers O atoms to the substrate. In this context, the oxidizing agent can be called an oxygenation reagent or oxygen-atom transfer agent. Examples include [MnO4]- permanganate, [CrO4]2- chromate, and OsO4 osmium tetroxide. Notice that these species are all oxides, and in fact, polyoxides. In some cases, these oxides can also serve as electron acceptors, as illustrated by the conversion of i do not believe this [MnO4]– to [MnO4]2-, manganate.
