It is well known that sodium is a waxy element derived from alkali metals, which is abundant in nature as compounds. It should be noted that this is a chemically active element characterized by silvery-white. Also, present in salt and represents sodium B (Na). It should be noted that it is the most common alkali metal and the sixth most abundant element: in addition to reproducing in the soil, it also represents 2.8% of the earth’s crust. In the form of (NaCl), it is a metal salt dissolved in seawater.
In the periodic table, atomic number = 11 mass number 23 sodium distribution of electrons 1S 2, 2S 2 2P 6, 3S 1
It is a very effective silver-white metal, belonging to the base metal family and constituting the first group of the periodic table. In 1807, Humphrey Davy, who had been involved in the electrolysis of sodium hydroxide, separated it for the first time. .
Generally, in 1912, Downs succeeded in producing commercial quantities of Downs in the electrolysis of a molten mixture of sodium chloride and calcium chloride. chemistry analysis
A Na derivative named in Arabic (a plant with high sodium content) Sodium carbonate is an ancient name for salt.
It is also said that the origin of the sect is Latin and German natron. This term indicates the presence of this salt on the shores of Lake Pattern.
The sodium content was 2.83%. The earth’s crust is the most widely distributed element in nature.
This element is not freely available in nature because it oxidizes rapidly in the air and reacts violently with water, that is to say, that it must be stored in a non-oxidizing medium.
The most important sources of sodium are rock salt (NaCl), Corona NaHC03 (Trona) Na 2 CO 3 .2H 2 O and sulfur salts. Sir Humphrey Davy directed the elaboration of the free element of Na, without interaction with any other element, in 1807, and because it is very reactive and never exists freely in nature, Humphrey Electrolysis is applied on dissolved sodium hydroxide. Sodium, hydroxide-NaOH).
It is obtained by heating old caustic sodium with a mixture of carbon and iron at a temperature of 1000 ° C. o Based on the following interactions:
More recently, it has been prepared by electrolysis of a molten mixture of sodium chloride (40%) and calcium chloride (60%) or sodium fluoride. To this end, cell analysis is called Down cells. The mixture is melted at 580 ° C or is the temperature at which the battery operates.
