The discovery of benzene rings
By: Lavinia T
Benzene is considered as one of the fundamental structures in organic chemistry. Benzene has several applications in the manufacturing industry. However, the structure benzene attracted lot of attention when it was first discovered in the 19th century. Michael Faraday was the scientist who first discovered...
The chemical properties of acids and bases
By: Lavinia T
Substances are generally classified as acids, bases and neutral. To determine whether a substance is acidic, basic, or neutral, we can generally make use of indicators. If a substance is acidic, then it would turn blue litmus red. On the other hand, if a substance...

The word “electrum” has invaded modern language. We see it pop up in such diverse places as the Star Wars universe, numerous fantasy games, and occasionally in a scientific context. Given the awareness of the word it might be surprising that there is just...
Overview of the Schroedinger equation in chemistry
By: Tarek Musslimani
The Schroedinger equation is a quantum mechanical differential equation that describes the energetics of atoms and molecules. In addition, its solution of atomic and molcular wavefunctions gives the shape and energy of the various atomic and molecular orbitals of the molecule under investigation. The Schroediger...
