Sodium (Katie Carrico)

  1. 1. Katie Carrico
  2. 2.  Sodium comes from the Latin word natrium where is where it gets it symbol Na. In English sodium comes from the word soda which means headache remedy. It was discovered in England by Sir Humphrey Davy
  3. 3.  Sodium is a silvery white solid at room temperature, but it is a very soft solid. Melting Point: 97.72˚C. Boiling Point: 883˚C. Density at 293 K: 0.971 g/cm3 Because sodium is an alkali metal, it is a good conductor of heat and electricity.
  4. 4.  Sodium-23 is the only naturally occurring isotope of sodium. There are six known radioactive isotopes of sodium. The two major radioactive isotopes are sodium-22 and sodium-24.
  5. 5.  Sodium 22 and 24 are used in medicine. • They are used as tracers to follow sodium in a person’s body. • The radiation given off by the isotopes are followed by detectors. Sodium-24is also used to test leaks in underground oil pipelines. • Sodium-24 is added to the pipelines and when the oil leaks, so does the sodium-24 which can easily be detected by radiation detecting instruments.
  6. 6.  Sodium is not found free in nature because it is highly reactive. It is very abundant in the sun and stars, and is even found in the earth’s crust. Sodium can be obtained by passing an electric current through molten NaCl. Cost: $25 per 100 g.
  7. 7.  Pure sodium has very few uses because it is such a reactive element. Metallic sodium is used to manufacture organic compounds. It is also used to remove impurities from molten metals. Metals can be separated from compounds using sodium. It is used as a heat exchange medium in nuclear power plants. The heat in sodium converts water to steam which generates electricity.
  8. 8.  Sodium is used to make artificial rubber. It is used in making light bulbs. Sodium is converted to gas and injected into the light bulb. An electric current causes sodium vapor to give off a yellowish glow. Sodium vapor lamps are popular today because they do not produce as much glare as ordinary lights.
  9. 9.  Sodium chloride- seasoning, preservative, synthesis of other sodium compounds Sodium hydroxide- film, rayon, soaps, paper, and lye Sodium carbonate-glass making, paper production, textile manufacturing, soaps, and detergents Sodium bicarbonate-baking soda Sodium sulfate-cardboard and Kraft paper
  10. 10.  Sodium silicate- Soaps, detergents, adhesives, water treatment, and bleaching and sizing textiles. Sodium borate-borax Monosodium glutamate-MSG
  11. 11.  Sodium is the most abundant alkali metal. Sodium is stored in oil to prevent its reaction with air. Pure sodium mixed with water creates a violent reaction. So much energy is released that the sodium melts, turns into a ball, and the heat causes the hydrogen gas to explode, and the sodium ball sizzles across the water. http://www.youtube.com/watch?v=92Mfric7JU c&feature=related
