Definition
Real-world examples
Importance
Reaction between an acid and a base resulting in
the formation of salt and water.
Occurs in numerous industrial processes and is
essential for life processes.
Mixing of vinegar (acid) and baking soda (base)
to create carbon dioxide gas.
6
Oxidation-Reduction Reaction
Definition
Real-world examples
Applications
Electron transfer between atoms or molecules.
Used in batteries, metal production, and numerous
other chemical processes.

• Photosynthesis in plants involves the oxidation
  of water and the reduction of carbon dioxide to
  make glucose.

• Burning of fuels involves the oxidation of
  hydrocarbons to release energy.

7
Precipitation Reaction
Definition
Real-world examples
Applications
A reaction in which two soluble compounds in a
solution combine to form a solid (a precipitate)
that settles out of the solution.
Carbonate ions in seawater react with calcium
ions to form calcium carbonate shells for marine
organisms.
Used in water treatment, wastewater treatment,
and mineral processing.
8
Complexation Reaction
1
Definition
A reaction between a metal ion and a ligand (a
molecule or ion that surrounds the central metal
ion) to form a complex.
2
Real-world examples
Iron in our blood is bound to the protein
hemoglobin in a complexation reaction.
3
Applications
Used in biological processes, analytical
chemistry, and industrial processes such as
dyeing and printing fabrics.
