2.2 Balancing of Equations
There are two main methods to balance redox equations: 1. Redox Method (Oxidation Number Method) 2. Ion-Electron Method (Half-Reaction Method) Both methods are based on the fundamental principle that in a redox reaction, the total number of electrons lost by the substance being oxidized
