Function of Inorganic Chemistry (continued)


Oxides

Oxide is every substance formed by oxygen and another element. They form binary compounds, that is, they have only two elements in their chemical formula.

Examples: Na2O, MgO, Al2O3, FeO.

Oxides are identified as binary compounds, with oxygen being the most electronegative element on the right side of the formula. Therefore, there is no fluorine oxide.

Utility

- Calcium Oxide (CaO) - white solid used in construction to manufacture cement, brick, ceramics. Acts as fungicide and bactericide. In agriculture, it is used to correct soil acidity. It can be called quicklime or virgin lime.

- carbon dioxide (CO2) - is carbon dioxide obtained as a byproduct of various industrial reactions. Used in soft drinks and when solid is known as dry ice. Participates in photosynthesis of plants.

- hydrogen oxide (H2O) - is the water. Most important oxide on the planet. All life on earth is associated with this oxide.

- Zinc Oxide (ZnO) - is a white powder (whitish) used in clown face paints. Also used as sunscreen.

- Hydrogen Peroxide (H2O2) - called hydrogen peroxide, is a rapidly decomposing peroxide. It is used as a bactericide and for bleaching hair, fibers and paper.
