Redox
Reactions
Redox reactions are oxidation-reduction
chemical reactions in which the reactants
undergo a change in their oxidation states. The
term ‘redox’ is a short form of reduction-
oxidation. All the redox reactions can be broken
down into two different processes: a reduction
process and an oxidation process
What are
Redox reactions
A redox reaction can be defined as a chemical
reaction in which electrons are transferred between
two reactants participating in it. This transfer of
electrons can be identified by observing the changes
in the oxidation states of the reacting speciesThe
substance getting reduced in a chemical reaction is
known as the oxidizing agent, while a substance that
is getting oxidized is known as the reducing agent.

Rusting Of Iron
Rusting of iron is a common redox reaction that we
observe in our daily life. When iron is exposed to
moist air, it reacts with oxygen to form iron(III) oxide,
commonly known as rust. This is an oxidation
reaction as iron loses electrons to form iron(III) ions.
At the same time, oxygen is reduced as it gains
electrons to form oxide ions. This reaction is slow and
can take a long time, which is why we see rust
forming over time on iron objects left exposed to the
air
Respiration
Respiration in humans is another example of a
redox reaction. It is the process by which our
bodies convert glucose into energy. During
respiration, glucose is oxidised to carbon dioxide
and water, releasing energy. Oxygen acts as the
oxidising agent, accepting electrons from glucose.
This is a continuous process that occurs in all living
cells to provide the energy needed for various
bodily functions.
Burning of Fuels
The burning of fuels is a redox reaction that we
often see in our daily life. When a fuel, such as
wood or petrol, is burnt, it reacts with oxygen in
the air to produce heat, light, carbon dioxide, and
water. This is an oxidation reaction as the fuel
loses electrons. Oxygen is reduced as it gains
electrons. This reaction is exothermic, meaning it
releases energy, which is why we use fuels for
heating, cooking, and powering vehicles.
Batteries
Redox reaction is the main point of the process of
charge and discharge of battery. For example, in
alkaline batteries, as the current flows through
the zinc and manganese dioxide, an
electrochemical reaction leading to the
production of electricity occurs.
Just like in lithium-ion battery, the redox reactions
between lithium ions and electrodes are
responsible for their working.
Photosynthesis
Photosynthesis, which is the reaction in which the
green plant, algae, and some of the bacteria
transform light energy into chemical energy in
the form of glucose, is considered as an
irreversible redox reaction. Plants, during
photosynthesis, absorb light energy which is then
converted to chemical energy by the process of
reduction of carbon dioxide to glucose using the
chlorophyll. Likewise, water molecules are
stripped away of their oxygen atom.
Conclusions
Redox reactions are integral to many everyday
processes. They are essential for energy production,
biological functions, and industrial applications.
Understanding these reactions helps in various
fields including health, environment, and
technology.
