What are examples of redox reactions?
Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Some examples of common redox reactions are shown below. CH A 4 ( g) + 2 O A 2 ( g) → CO A 2 ( g) + 2 H A 2 O ( g) ( combustion of methane)
What are oxidation reduction reactions?
Oxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.
Can oxidation numbers identify redox reactions?
In other cases, however, it is not as obvious, particularly when the reaction in question involves only nonmetal substances. To help identify these less obvious redox reactions, chemists have developed the concept of oxidation numbers, which provides a way to track electrons before and after a reaction.
