Two key types of chemical reactions are oxidation and reduction.

Here is another mental exercise: An oxidizing agent oxidizes something else.According to this definition, oxidation is the loss of hydrogen, while reduction is the gain of hydrogen.While the addition of oxygen to a compound typically meets the criteria of electron loss and an increase in the oxidation state, the definition of oxidation was expanded to include other types of chemical reactions.Oxidation and Reduction with respect to Oxygen Transfer.In the equation, the carbon monoxide is the reducing agent.(as modifier an oxidation-reduction reaction.Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012.

Oxidation is loss of electrons (OIL RIG).
Electrochemical reactions are great examples of oxidation reactions.
H2 2 H.
Therefore, an oxidizing agent must gain electrons.A reducing agent reduces something else.The LibreTexts libraries are Powered by MindTouch and are based upon work supported by the National Science Foundation under grant numbers: 1246120, 1525057, and 1413739. .The iron is said to have oxidized into rust.Oxidation and reduction in terms of hydrogen transfer.Again the equation is too complicated to consider at this point.Some ignore it for as long as possible, hoping that it is a temporary phase that will go away soon.Reducing agents remove oxygen from code carte cadeau voyage privé another substance.Therefore, an oxidizing agent takes electrons from that other substance.Dorling Kindersley / Getty Images.

An oxidizing agent is substance which oxidizes something else.
Oxidation and reduction in terms of electron transfer.
Therefore, the oxidizing agent must be reduced.
