Redox reactions pair oxidation with reduction and can be recognised through oxygen, hydrogen or electron transfer.
Open article →Oxidation Number: Meaning and Core Rules
Oxidation number is an assigned charge whose algebraic sum matches the overall charge of a species.
Open article →Oxidation Number Rules, Exceptions and Calculations
Hydrogen, fluorine, oxygen and group-metal rules include defined exceptions and support algebraic calculations.
Open article →Oxidation-State Change and Redox Agents
An increase marks oxidation, a decrease marks reduction, while agents undergo the opposite named change.
Open article →Types of Redox Reactions with Equations
Combination, decomposition, displacement and disproportionation are recognised from reaction pattern and oxidation-state change.
Open article →Competitive Electron Transfer: Zn and Cu
