CHEMISTRY AND ITS BRANCHES

Chemistry is the science of substances - of their structure, their properties, and the reactions that change them into other substances

The study of chemistry may be divided into the following branches:

- General chemistry, which is an introduction to the entire science

- Qualitative analysis, giving the methods of testing for the presence of chemical substances

- Quantitative analysis, giving the methods of accurate determination of the amounts of different substances present in

a sample of material

- Inorganic chemistry, which is the chemistry of elements other than carbon, and their compounds

- Organic chemistry, which is the chemistry of the compounds of carbon

- Physical chemistry, which studies the quantitative relations among the properties of substances and their reactions

- Biochemistry, which is the chemistry of the substances comprising living organisms

- Structural chemistry, which deals with the molecular structure and its relation to the properties of substances

- Radiochemistry, which is the chemistry of radioactive elements and of reactions involving the nuclei of atoms

- Industrial chemistry, which is concerned with industrial processes

Although chemistry is a very large and complex subject, which still continues to grow as new elements are discovered or made, new compounds are synthesized, and new principles are formulated

The chemists or chemical engineers need to have some knowledge of all its branches, even if he may be specialized in a particular line

Chemistry science cannot do without physics and mathematics, and is also closely linked to some other sciences, e.g inorganic chemistry is linked closely to geology, mineralogy, and metallurgy, while organic chemistry is linked to biology

in general
