Redox Reactions

Redox reactions can be categorized into two distinct processes, namely oxidation and reduction. The redox reaction, commonly referred to as the Oxidation-Reduction reaction, always includes the simultaneous occurrence of oxidation and reduction phenomena. In the context of a chemical reaction, … Read more

Isomerism

Isomerism occurs when many substances have the same chemical formula but different chemical structures. The term “isomer” comes from the Greek words “isos” and “meros,” both of which signify “equal parts.” In the year 1830, the Swedish chemist Jacob Berzelius … Read more

Azo Compounds (A Level Chemistry Revision Notes)

Azo compounds

Azo compounds are the compounds of both natural and manufactured chemicals that contain at least one azo group (N=N) in their structure. The atomic groups connected to the nitrogen atoms might be of any organic class, but the commercially relevant azo … Read more

Hydrogen Embrittlement: Causes, Types, Prevention

hydrogen embrittlement

Hydrogen embrittlement is a loss of ductility caused by excessive hydrogen absorption, rendering the material brittle. This isĀ because hydrogen atoms are substantially smaller than those that make up the deposited metal. This causes hydrogen atoms to migrate into the base … Read more
