Oxide function

Oxides are composed of only two chemical elements (binary compounds), where one of them must be oxygen.

The two most characteristic examples of oxides are water (H2O), present in almost everything on our planet, and carbon dioxide (CO2), used for example by food chain producers in the process of photosynthesis.

Binary compounds formed by oxygen and fluorine are not considered oxides because their properties differ from oxides in general.

Oxides can be formed by combining oxygen with almost all the elements of the periodic table, metals and ametals. They are found in the form of numerous minerals, especially iron ore (Fe2O3), called hematite, and aluminum ore (Al2O3), called bauxite. These ores are used to obtain metallic iron and aluminum.

Oxides are binary compounds formed by oxygen and another chemical element other than fluorine.

Peroxides: In industry they are used as fabric clarifiers (bleaches), cellulose saver, etc. For these uses its concentration is greater than 30% hydrogen peroxide. The 3% hydrogen peroxide aqueous solution, popularly known as hydrogen peroxide, is used as an antiseptic and some people use it for hair and hair discoloration.

Silicon dioxide: is the most abundant oxide of the earth's crust, it is one of the components of crystals, rocks and sand.

Calcium Oxide (CaO): Obtained from limestone decomposition, is used in agriculture to decrease soil acidity and also in the preparation of mortar in construction.

Nitrous Oxide (N2O): Known as hilarious gas, this small amount inhaled oxide causes euphoria, but can cause serious health problems; It is used as an anesthetic.

Sulfur Dioxide (SO2): It is used to obtain sulfuric acid and bleaching food oils, among other applications. It is one of the main air pollutants; On humid days, it combines with water vapor from the atmosphere and causes the so-called acid rain.

Carbon Monoxide (CO): Used to obtain certain chemicals and steel metallurgy. It is usually the main air pollutant of urban areas; inhaled combines with the hemoglobin of the red blood cells, neutralizing them for the transport of oxygen gas in the body.
