The Chemical Element Sodium (Na) In Chemistry

Sodium is an alkali metal elements white-silver, highly reactive metal and is soft. Sodium can react violently with water to form sodium hydroxide and hydrogen gas.



The element sodium found in nature in the form of mineral salts such as sodium chloride (NaCl), sodium carbonate (Na2CO3), and sodium sulfate (Na2SO4). To obtain sodium can be made by electrolysis of molten NaCl.

Important data about the Sodium:
  1. Discovered by Humphry Davy in 1807
  2. Has atomic mass 11
  3. Has atomic radii 1.90 A
  4. Has electron configuration 2 8 1
  5. In compound has an oxidation number + 1
  6. Has the Atomic volume of 23.70 cm3/mol
  7. Have a bcc crystal structures
  8. Has boiling point 1156 K
  9. Has a melting point of 371.0 K
  10. Has density 0.91 g/cm3
  11. Has heat capacity J/g 1.23 K
  12. Has 5.139 volt ionization potential
  13. Have elektronegatifitas 0.93
  14. Have the electrical conductivity of 20.1 x 106 ohm-1 cm-1
  15. Have a heat conductivity of 141 W/mK
  16. Has the price formation enthalpy 2.601 kJ/mol
  17. Has a value of enthalpy of vaporization 98.01 kJ mol.

Some of the uses of sodium:
  1. Used in the manufacturing process TEL (tetraethyl lead)
  2. Used in nuclear reactor cooling tool
  3. Salt (NaCl) is used as a condiment Cook
  4. Nstrium bicarbonate (baking soda) is used in the manufacture of pastry
  5. Sodium hydroxide (soda) is used in the process of making SOAP, rayon, paper, oil refining and the rubber industry textile industry
  6. Sodium tetraborat (borax) is used as a preservative
  7. Sodium Flourida (naF) is used as rat poison and antiseptic drugs insect repellent (e.g. cockroaches)
  8. Sodium nitrate (NaNO3) known as Chile saltpeter (Chile saltpeter) is used as a fertilizer
  9. Sodium peroxide (NaS2O2) is used as a bleach and strong oxidizing
  10. Sodium thiosulfat (NaS2O3.5H2O) used as drug anxiety disease injection (hypo) and used on the tools of photography.
