oxidován

Oxidován is a Czech word that translates to "oxidized" in English. It refers to the process of oxidation, which is a chemical reaction involving the loss of electrons. In simpler terms, it often describes a substance that has reacted with oxygen. This can lead to changes in the substance's properties, such as color, texture, or chemical composition.

Common examples of oxidation include the rusting of iron, where iron reacts with oxygen and moisture to form iron oxide. Another familiar example is the browning of a cut apple, where enzymes in the apple react with oxygen in the air. In biological systems, oxidation plays a crucial role in metabolism, where food molecules are broken down to release energy.

The term "oxidován" can also be used in a broader chemical context, not necessarily involving oxygen. Any process where an atom or molecule loses electrons is considered oxidation. This is often paired with a reduction process, where another atom or molecule gains electrons, forming a redox reaction. The extent of oxidation is described by oxidation states, which are hypothetical charges assigned to atoms in a compound.
