Inorganic Chemistry Definition|Examples & Applications

Inorganic chemistry is the branch of chemistry which deals with inorganic substances.

Inorganic substances can be both metallic and non-metallic substances in different forms.

They are exclusively called so because they are devoid of carbon.

They are mostly formed by ionic or covalent bonds.

They are mostly crystalline and solids in nature.

Inorganic Chemistry Definition:

“It is the subject dealing with synthesis, properties, reactions and the uses of compounds devoid of carbon.”

Table salt (NaCl) used for food

Some Experts add to the exception that compounds which do not contain carbon-hydrogen bond are also inorganic.

Inorganic chemistry is one of the widest subjects as it covers many substances approximating to few thousands.

Examples of inorganic chemistry include

1: Acids: HCl, H2SO4, HNO3, H3PO4 etc.

2. Bases: NaOH, Mg (OH)2, KOH, Ca(OH)2

3. Salts: NaCl, MgSo4, KCl, CaCl2.

4. Gases: Oxygen, nitrogen, CO2 etc.

5. Oxidizing agents: KMNO4, KClO4.

6. Reducing substances: NaHSO3 (sodium thiosulphate.)

Their reactions are also mostly by ionic bonds and also by covalent.

Most of them form just single bonds unlike organic compounds. organic compounds have multiple bonds in between two atoms occasionally. Also they can exist as electrolytes in the liquids. These electrolytes are charged ions and can move in the electric field.

Application of inorganic compounds.

The compounds are many so we find them in different set of uses in daily life.

Inorganic chemistry compounds find a lot of use in medicine and health care. The individual compounds and their uses are in the table below.

Examples of Inorganic Chemistry in medicine

Sl.NoInorganic compoundChemical formulaApplication & uses
1Magnesium hydroxide, Aluminum hydroxideMgOH
As antacids to relive acidity & heart burns
2Sodium chloride, potassium chloride NaCl, KCLAs oral re-hydration salts. To relieve weakness in time of dehydration, diarrhea or vomiting.
3Sodium nitrite,
Sodium thiosulphate
In cyanide poisoning & anti-oxidant
4Ferrous SulfateFeSO4In Anemia to enhance hemoglobin levels.
5Sodium fluorideNaFIn tooth paste to prevent dental caries
6OxygenO2For respiration

Besides medicine we also use them at home for daily needs. Some of the examples are in the table below.

Examples of Inorganic Chemistry at home

1Table salt (Sodium Chloride)NaClTo give salt taste to food.
2Baking sodaNaHCO3In making cakes and other stuff.
3Washing sodaNa2CO3Used in washing of clothes
4Bleaching powderCaoCl2Used in cleaning and sterilizing drinking water, swimming pools etc.

Also inorganic substance include all the minerals used in decoration items like talc, bentonite, steatite etc.

Besides many ceramic products are mad by use of sand and other inorganic substances in combination. Even the electric circuits in computers are made of silicon which is sand like substance. Hence the name silicon valley to the place of high use of computers.

Unlike organic compounds, they do not get spoiled when stored. They are also very stable to a large extent. They are comparatively cheaper and easily available.
