Oxidation-Reduction (Redox) Reactions (4.4) “Redox” reactions: Oxidation & reduction always occur simultaneously. We use . OXIDATION NUMBERS. to keep track of electron transfers. Rules for Assigning Oxidation Numbers: 1) the ox. state of any free (uncombined) element is zero. Ex: 2) The ox. state of an element in a simple ion is the charge ...

EXAMPLES: 2 Fe2 O3 + 3 C ( 4 Fe + 3 CO2 Fe: +3 to 0; Fe is reduced, Fe2O3 is the oxidizing agent. ... These reactions are used to balance redox equations. The reaction is broken into two parts – the oxidation part and the reduction part. The half –reaction method allows you to apply your knowledge of oxidation numbers in order to balance ...

WRITING IONIC EQUATIONS FOR REDOX REACTIONS. This page explains how to work out electron-half-reactions for oxidation and reduction processes, and then how to combine them to give the overall ionic equation for a redox reaction. This is an important skill in inorganic chemistry. Don't worry if it seems to take you a long time in the early stages.

Redox reactions are usually synthesis reactions, decomposition, combustion or single replacement reactions. Double replacement and neutralization reactions are NOT redox reactions. Usually they are easy to spot because if an element goes from being “free” (with an oxidation number of 0) to being in a compound (with a new oxidation number ...
