how to tell which species is oxidized and reduced
In redox processes, the reductant transfers electrons to the oxidant. Thus, in the reaction, the reductant or reducing agent loses electrons and is oxidized, and the oxidant or oxidizing agent gains electrons and is reduced.The pair of an oxidizing and reducing agent that are involved in a particular reaction is called a redox pair.here are simple redox processes, such as the oxidation of carbon to yield carbon dioxide (CO 2) or the reduction of carbon by hydrogen to yield methane (CH 4), and more complex processes such as the oxidation of glucose (C 6 H 12 O 6) in the human body through a series of complex electron transfer processes.
