BASIC CHEMICAL CONCEPTS
... Chemistry may be defined as the study and practice of making basic materials and determining their character. This embraces “pure” chemistry (“the study…”) and “applied” chemistry (“the practice…”) (cf. Nelson, 1983). It also includes the preparation of mixtures, other than by simple mixing of compo ...

Inorganic chemistry
Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds (carbon based compounds, usually containing C-H bonds), which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, and there is much overlap, most importantly in the sub-discipline of organometallic chemistry. It has applications in every aspect of the chemical industry–including catalysis, materials science, pigments, surfactants, coatings, medicine, fuel, and agriculture.
