20 Examples of Acidic Oxides

The acid oxides, also called non-metallic oxides or anhydrides, arise from the combination of a non-metal with oxygen. Since the electronegativity difference between these elements is low, the bonds that form between them are covalent. For example: arsenic oxide, carbon dioxide, tellurium oxide.

When reacting with water, these compounds form oxacid acids, but if they are in the presence of hydroxides, what is formed is a salt and water. Several of these compounds are gaseous substances.

Both the point of boiling of these compounds such as fusion they are usually low. Acidic oxides or anhydrides obey the generic formula X₂OR_n, where the X represents some non-metallic element.

Acidic oxides are widely used in industry for different purposes. For example, carbon dioxide is used in the production of carbonated beverages. Also some acid oxides are toxic, such as carbon monoxide, which has caused so many deaths associated with the use of stoves with combustion incomplete indoors.

Also toxic are sulfur and nitrogen oxides

, often causing the depletion of the ozone layer. Titanium oxide, for its part, has great importance as a pigment, it gives white color.
