WebA half equation is an equation that shows one-half of a redox reaction. Each half equation represents either the process of oxidation or reduction in terms of electron movement. For example, the reaction between bromine and iodide ions has the following two half equations: Br 2 + 2e - → 2Br -. 2I - → I 2 + 2e -. WebApr 7, 2024 · The Half Equation Method is used to balance these reactions. In a redox reaction, one or more element becomes oxidized, and one or more element becomes reduced. Oxidation is the loss of electrons whereas reduction is the gain of electrons. An easy way to remember this is to think of the charges: an element's charge is reduced if it …
