Understanding Oxidation


Understanding Oxidation - Oxidation is a process of direct contact interaction between oxygen molecules and all the substances different from inanimate objects to living tissue such as plants. Technically, with the discovery of the electron, oxidation is more precisely defined as a loss of at least one electron when two or more substances interact. Oxidation will occur when contact between free radicals and air elements such as oxygen and water.

Oxidation can damage eg rust on a car, and the destruction of fresh fruit such as apples cut will change its color to brown. Not all materials that interact with molecules of oxygen crumble into rust, oxidation but also beneficial for the establishment of durable aluminum.

Oxidation is also a process of releasing molecules, ions, or atoms that contain electrons in the air, these substances may or may not include oxygen. Oxygen creates a slow combustion process, which produces a substance we call a brittle brown rust on metal objects made of iron for example. When oxidation occurs on copper, on the other hand, the result is a layer of greenish-called copper oxide.

In the case of iron, oxygen creates a slow combustion process, which produces brittle brown substance we call rust. When oxidation occurs on copper, on the other hand, the result is a layer of greenish-called copper oxide. Metal itself is not weakened by oxidation, but the surface patina develops after exposure to many air and water.

Reduction is the opposite of oxidation meruapakan substances that reduce another substance. Oxidation is gain of oxygen, while the reduction is the loss of oxygen. Reduction and oxidation occur simultaneously. So that this reaction is called a redox reaction.
