Oksidansi
Oksidansi, also known as an oxidizing agent or oxidant, is a substance that tends to cause oxidation in another substance during a chemical reaction. Oxidation is a process where a molecule, atom, or ion loses electrons. Therefore, an oxidant is a species that accepts electrons. In this electron transfer process, the oxidant itself gets reduced, meaning it gains electrons. Common examples of oxidants include oxygen (O2), hydrogen peroxide (H2O2), halogens like chlorine (Cl2) and bromine (Br2), and permanganates (like KMnO4). The strength of an oxidant is determined by its tendency to accept electrons, often measured by its standard electrode potential. Oxidants are crucial in various chemical processes, from combustion and respiration to industrial applications like bleaching and disinfection. Their ability to readily accept electrons makes them powerful tools in synthesis and analysis. When an oxidant reacts with a reductant (a reducing agent), which is a substance that loses electrons, an oxidation-reduction (redox) reaction occurs. The oxidant is consumed in this reaction as it transfers its electrons. The overall process involves the transfer of electrons from the reductant to the oxidant.
