Oxidation is a chemical reaction that changes the substance by adding oxygen to it. The oxidation process can be either spontaneous or chemically induced. When you hear about an atom being oxidized, what it really means is that electrons are being lost in this process. Reduction is the opposite of oxidation, and it means removing oxygen from an atom, which in turn reduces the number of electrons.
So, what does that have to do with oxidized? reduced? Well, it’s important for substances to maintain a state of equilibrium between their oxidation and reduction processes. The concept is often expressed as the redox ratio: “reduced: oxidized.” If this number becomes too high or low, then these reactions can accelerate because they are in more extreme states than what we’re used to.
A substance will become an oxide when there are electrons lost from its atoms during oxidation. Nitrogen dioxide (NOₓ) is one example; here oxygen has been added onto the nitrogen atom so now it contains both NO and O₂ molecules instead of just N₅ ones like before. This molecule was once a neutral N₅ molecule, but now it has gained an O and turned into an oxide.
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-. The newly-added electron reduces the charge from +H down to -H+, making this oxidized water molecule completely safe for us to consume!
The reason why we enjoy chemicals like these so much is that they often have different properties than their unoxidized or unreduced counterparts; think about how dissimilar salt tastes after being put through a chemical process that oxidizes it.
An example of an improved macroscopic property would be that a substance becomes more soluble when it is reduced.
In terms of oxidation numbers, reducing something will typically have the opposite effect; for example, aluminum metal being oxidized would become an Al+ ion and oxygen gas (O) because in this case electrons are added to its atoms during reduction.
This article touches on what happens to substances that go from hydrated electron-rich molecules or ions with +H+, such as HCl(aq), NH+ (), HO− () into hydrogen peroxide (HO). This reaction takes place by combining these two compounds: acid plus base = salt plus water! Hydrogen chloride reacts with ammonia which produces ammonium bicarbonate–NHCO. The result? Ammonia combines with water to create an ionic salt–ammonium bicarbonate.
The oxidation level of a substance is an indicator of the rate at which it will rust. Oxidation can be described as a process that transfers electrons from one atom to another or one molecule to another. This transfer creates what’s called an oxidizing agent, and this compound or element changes its character due to acquiring oxygen atoms during the reaction. The term reduction refers to when these same compounds lose their excess number of oxygen atoms in order to balance out their electron count with those on other molecules.
A substance does not have any net change if it undergoes both oxidization and reduction reactions simultaneously because they are always happening together; however, substances usually experience more of either type depending on external conditions they’re exposed too such as air and water.

Oxidization: A compound undergoes oxidation if its molecules are losing one or more electrons—that is, becoming less electrically negative (-). This type of change occurs all the time in nature but may also result from chemical reactions with oxygen (O) outside cells.
Reduction: A compound undergoes reduction if its molecules are gaining one or more electrons—that is, becoming less electrically positive (+). This type of change occurs all the time in nature. It can also occur outside cells when a chemical makes an electron available to react with another molecule.
Oxidation happens when an atom loses electrons (loses -) which produces reactive oxygen species such as hydroxyl radical (.OH), superoxide ion (O-, O,) hydrogen peroxide (), singlet oxygen ( ), hydroxyl free radical (), and atomic chlorine (). Hydrogen peroxide oxidizes water into molecular oxygen and breaks down fats, proteins, carbohydrates to their original sugars ̶ glucose, fructose from fruit sugar sucrose, etc.,
