What is inorganic chemistry
Inorganic chemistry is the chemistry of non-biological materials, that is, materials free of carbon-hydrogen (carbon and hydrogen) such as salts and minerals. It is concerned with studying the components of these substances and their physical and chemical properties, unlike organic chemistry. Inorganic chemistry includes many fragmented research areas such as
- Solid-state chemistry.
- Coordination Chemistry.
- Mineral organic chemistry.
- Surface chemistry.
- Media chemistry.
- Molecular chemistry.
- Polymer chemistry.
Inorganic chemistry tends to specialize in the study of catalysts, paint, fuel, superconductors, and drugs, and its chemical reactions are based on the principle of double displacement, acid-base reactions, and oxidation-reduction reactions.
Characteristics of inorganic compounds
Many of the inorganic compounds studied by inorganic chemistry have the potential to conduct electricity, aided by the mineral elements in their components. For example, in solid states, their conductivity of electricity is less, while in liquid media it has a high potential for transporting electricity, where the electrons of inorganic compounds move freely, and this free movement is defined as electricity.
Inorganic compounds hold together very firmly, affected by the ionic bonding between their atoms, and they are characterized by very high melting and boiling points. The most characteristic of inorganic compounds is their color. Transitional metallic elements thereof and others carry very strong colors, and the reason for this is a variety of electrons called “d-block”, and this explains to us the aesthetic colors issued by the fireworks explosion as they carry in their components compounds Inorganic gives a distinct color when burning, and this can be used to identify a mineral.
Inorganic compounds also have the property of dissolving in water, when put in water dissolve it to the point of disappearing. In addition, inorganic compounds are able to form crystalline structures, and the bonding found in inorganic compounds enables the formation of crystalline structures in saturated solutions.
Examples of inorganic compounds
- Water H2O: It is a simple compound and is classified as an inorganic compound despite the presence of hydrogen (which is the main component with carbon in organic compounds) in its composition, but the hydrogen atoms in it formed simple bonds due to a lack of carbon.
- Hydrochloride or HCl: Also known as hydrochloric acid when dissolved in water, it is a corrosive colorless acid with a strong pH. This acid, which is found in the infectious juices of some animals, helps in digestion and makes it easier by destroying food.
- Carbon dioxide CO2: it is an inorganic compound although it contains carbon, and this thing has caused differing opinions among chemists with many inquiries and ambiguous answers regarding the validity of current methods of classification of compounds. Organic compounds are made of carbon or hydrocarbon, which forms a stronger bond, whereas the carbon in the carbon dioxide components forms bonds that are not strong.
- NO2: Its color varies with temperature, it has many colors. It is often caused by nuclear tests in the atmosphere. It gives the red color to withdraw the distinctive mushrooms of the nuclear explosions, it is also highly toxic and forms weak links between nitrogen atoms and oxygen.
- Fe2O³: Iron oxide (3) is one of the three major iron oxides, classified as an inorganic compound due to its lack of carbon or hydrocarbon. Iron oxide is obtained automatically like hematite (which is one of the most important sources of iron in the steel production industry). It is known as rust and shares a number of properties with its natural counterpart
