Sodium is an alkali metal of group 1. The atomic number of sodium is 11. It is a soft, white, highly reactive alkali metal. It has one electron in the outermost shell, on losing it, it forms a sodium ion. Sodium do not occur free in nature as it is highly reactive. It is kept in kerosene oil to prevent its reaction in the atmosphere. It has mainly three minerals such as sodalite, feldspar, and rock salt. Rock salt is commonly known as Sodium Chloride (NaCl).


Properties of Sodium
It is highly reactive alkali metal.

It is soft, can be easily cut with knife.

The melting and boiling point of sodium is lower than that of lithium.

It possesses metallic bonding. It is also conducting in nature as it has one free electron.

It appears yellow in flame test.

It has lower first ionization energy.

The common oxidation state of sodium atom is +1.

Uses of Sodium
Sodium ions are primarily found outside the human cells such as nerve cells

They regulate the flow of water across the membrane

They are needed for transport of sugars and amino acids into the cells.


Important Compounds of Sodium are as Follows-
The most important compounds of sodium that are of commercial importance are as follows-


Sodium Carbonate
It is commonly known as Washing Soda with molecular formula Na2CO3.10H2O.

It is synthesized by Solvay process. During this process, sodium carbonate is synthesized using sodium chloride and calcium carbonate.

2 NaCl + CaCO3→ Na2CO3+ CaCl2

The steps for the formation of:

During first step, sodium chloride reacts with ammonia, carbon-dioxide and water to form sodium bi-carbonate.

NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl

During the second step, calcium carbonate is converted into calcium oxide and calcium carbonate.

CaCO3 → CO2 + CaO

Sodium bicarbonate reacts with calcium oxide from the step 2 to form ammonia, calcium chloride and water

2 NH4Cl + CaO → 2 NH3 + CaCl2 + H2O

Sodium bicarbonate finally decompose into sodium carbonate.

2 NaHCO3 → Na2CO3 + H2O + CO2

Sodium carbonate is readily soluble in water.

Heating of sodium carbonate decahydrate leads to the formation of sodium carbonate monohydrate. On further heating, monohydrate is converted into anhydrous form of sodium carbonate (without water).
