Oxidation-reduction reactions or redox reactions caninvolve the transfer of one or more electrons.
Oxidation - Reduction Reactions - Purdue University
The key to identifying oxidation-reduction reactions is recognizing when a chemicalreaction leads to a change in the oxidation number of one or more atoms. It is therefore agood idea to take another look at the rules for assigning oxidation numbers. Bydefinition, the oxidation number of an atom is equal to the charge that would be presenton the atom if the compound was composed of ions. If we assume that CH4contains C4- and H+ ions, for example, the oxidation numbers of thecarbon and hydrogen atoms would be -4 and +1.
According to this model, CO2 is reduced when it reacts with hydrogen becausethe oxidation number of the carbon decreases from +4 to +2. Hydrogen is oxidized in thisreaction because its oxidation number increases from 0 to +1.
Oxidation-reduction reactions or redox reactions can involve ..
The word metathesis literally means "interchange" or"transposition," and it is used to describe changes that occur in the order ofletters or sounds in a word as a language develops. Metathesis occurred, for example, whenthe Old English word brid became bird. In chemistry, metathesis is usedto describe reactions that interchange atoms or groups of atoms between molecules.
When at least one atom undergoes a change in oxidation state, the reaction is anoxidation-reduction reaction. Each of the reactions in the figure below is therefore anexample of an oxidation-reduction reaction.

We find examples of oxidation-reduction or redox reactions almostevery time we analyze the reactions used as sources of either heat or work. When naturalgas burns, for example, an oxidation-reduction reaction occurs that releases more than 800kJ/mol of energy.
Within our bodies, a sequence of oxidation-reduction reactions are used to burn sugars,such as glucose (C6H12O6) and the fatty acids in the fatswe eat.

OXIDATION And REDUCTION, balancing redox reaction
The tarnishing of silver is just one example of a broad class of oxidation-reductionreactions that fall under the general heading of corrosion. Anotherexample is the series of reactions that occur when iron or steel rusts. When heated, ironreacts with oxygen to form a mixture of iron(II) and iron(III) oxides.
reduction and oxidation reactions
Note that it doesn't matter whether the compound actually contains ions. The oxidationnumber is the charge an atom would have if the compound was ionic. The concept ofoxidation number is nothing more than a bookkeeping system used to keep track of electronsin chemical reactions. This system is based on a series of rules, summarized in the tablebelow.
What Is the Difference Between Oxidation and Reduction?
We don't have to restrict ourselves to reactions that can be used as a source ofenergy, however, to find examples of oxidation-reduction reactions. Silver metal, forexample, is oxidized when it comes in contact with trace quantities of H2S orSO2 in the atmosphere or foods, such as eggs, that are rich in sulfurcompounds.
These are called as metathesis reactions
Chemical reactions are often divided into two categories: oxidation-reduction ormetathesis reactions. Metathesis reactions include acid-base reactionsthat involve the transfer of an H+ ion from a Brnsted acid to a Brnstedbase.
"Difference Between Oxidation and Reduction."
Chemists therefore developed the concept of oxidation number to extendthe idea of oxidation and reduction to reactions in which electrons are not really gainedor lost. The most powerful model of oxidation-reduction reactions is based on thefollowing definitions.
Metathesis Reactions - Chemistry LibreTexts
Redox reactions are chemical reactions that involve the transfer of electrons from one atom to another. These reactions are very important. They occur in the operation of batteries, in the combustion of fuels, and in the corrosion of metals.
