The scope of chemistry
The science that we can define as the study of formation, composition,
structure and reactions of the chemical elements and their compounds is called
chemistry. Chemistry may be divided into the following branches: general,
analytical, organic and inorganic, physical, industrial, structural and
biochemistry. General chemistry is the introduction to the entire science.
Analytical chemistry deals with the methods of separation of pure substances
from mixtures. Physical chemistry is the study of relations between the
properties of substances and their reactions. Industrial chemistry is the chemistry
of industrial processes. Structural chemistry deals with the molecular structure
and its relation to the properties of substances. Radiochemistry is the chemistry
of radioactive substances and of reactions involving the nuclei of atoms.
