What happens to a substance when it becomes oxidized reduced
Jun 12, 2021 · A substance will become reduced when there are electrons added to its atoms during reduction. This is what happens with hydrogen gas because the proton in H+ can be transferred onto another atom (e.g., oxygen) which then becomes a hydroxide ion–OH-. Reduction of an organic compound results in a decrease in the number of carbon-heteroatom bonds, and/or an increase in the number of carbon-hydrogen bonds. Below are a number of common functional group transformations that are classified as redox. Heteroatoms such as oxygen and nitrogen are more electronegative than carbon, …

16.2: Oxidation and Reduction- Some Definitions. "Redox" is short for "oxidation and reduction", two complimentary types of chemical reactions. The term oxidation originally referred to substances combining with oxygen, as happens when an iron bar rusts or a campfire log burns. We often refer to these two examples as corrosion and combustion.Oxidation reaction: When oxygen combines with an element or compound, an oxidation reaction occurs. Oxidation can also be defined as the process of the removal of hydrogen from the reactant species. Oxidation is the process of losing electrons by a molecule, atom, or ion. For example, Mg → Mg 2 + + 2 e -.This can help us remember what reduction is, as the oxidation number gets reduced. The oxidizing agent is the species that undergoes reduction. It may be a little confusing initially, but always remember that the oxidizing agent causes another species to become oxidized. Redox reactions occur in pairs of reduction and oxidation.
