2007/12/17· An oxidising agent is substance which oxidises something else. In the above example, the iron(III) oxide is the oxidising agent. A reducing agent reduces something else. In the equation, the carbon monoxide is the reducing agent. Oxidising agents give oxygen to
Redox (shorthand for reduction/oxidation reaction) describes all chemical reactions in which atoms have their oxidation nuer (oxidation state) changed. This can be either a simple redox process such as the oxidation of carbon to yield carbon dioxide, or the reduction of carbon by hydrogen to yield methane (CH 4), or it can be a complex process such as the oxidation of sugar in the human body
