What is Biochemistry?

Originally a subdivision of chemistry but now an independent science, biochemistry includes all aspects of chemistry that apply to living organisms. Thus, photochemistry is directly involved with photosynthesis and physical chemistry with osmosis… two phenomena that underlie all plant and […]

What is Nuclear Chemistry

The division of chemistry dealing with changes in or transformations of the atomic nucleus. It includes spontaneous and induced radioactivity, the fission or splitting of nuclei, and their fusion, or union; also the properties and behaviour of the reaction products […]


Stoichiometry Defined:¬†Stoichiometry is the branch of chemistry and chemical engineering that deals with the quantities of substances that enter into, and are produced by, chemical reactions.¬† Stoichiometry provides the quantitative relationship between reactants and products in a chemical reaction. For […]

Physical Chemistry

Application of the concepts and laws of physics to chemical phenomena in order to describe in quantitative (mathematical) terms a vast amount of qualitative (observational) information. A selection of only the most important concepts of physical chemistry would include: the […]

Analytical Chemistry

Analytical Chemistry¬†is the subdivision of chemistry concerned with identification of materials (qualitative analysis) and with determination of the percentage composition of mixtures or the constituents of a pure compound (quantitative analysis). The gravimetric and volumetric (or “wet”) methods (precipitation, titration […]
