Application:
1.Manufacture of sodium Compounds, such as the cyanide, azide, peroxide, etc.; manufacture of tetraethyllead; manufacture of refractory metals; in org syntheses; for photoelectric cells; in sodium lamps; as catalyst for many polymerization reactions. Alloyed with potassium in heat transfer media.
2.This soft silvery metal occurring as chlorine in seawater was first isolated as an element by Humphry Davy in 1807. Sodium is one of the essential elements required by living organisms and it is highly reactive oxidizing in air and reacting with water. Sodium chloride was the first halide to be combined with silver for photographic purposes. Many of the sodium compounds were also used in gold toning baths. Some of them are included here.
3.Sodium is used in both low-pressure and high-pressure sodium vapor lamps. The low-pressure arc uses just a small amount of Na along with some neon for a starter. The lamp is economical and bright. The illumination with its single yellow color (electromagnetic frequency) makes it difficult for us to recognize other colors. In addition to sodium, the high-pressure lamp uses mercury, which provides a more natural color rendition of light. The very bright light of sodium-mercury lamps makes them ideal for use in sports stadiums and highways. Because the melting point of sodium metal is about 98 C (a bit lower than the boiling point of water), it is heated into a liquid phase and then transported in rail tank cars, where it cools and solidifies. Because sodium has a high specific heat rating, a major use is as a liquid coolant for nuclear reactors. Even though sodium (both solid and liquid) is extremely reactive with water, it has proven safe as a coolant for nuclear reactors in submarines. The natural deposits are located in northern Chile, which was the original source for many years. Of course, the most common use is everyday table salt, sodium chloride (NaCl).
4.Sodium is used in the manufacture ofmany highly reactive sodium compounds andtetraethyllead, as a reducing agent in organicsynthesis, and as a catalyst in the productionof synthetic rubber. It is also used in makingsodium lamp and photovoltaic cells.
Storage:
Safety glasses, impermeable gloves, and a fire-retardant laboratory coat should be worn at all times when working with sodium, and the metal should be handled under the surface of an inert liquid such as mineral oil, xylene, or toluene. Sodium should be used only in areas free of ignition sources and should be stored under mineral oil in tightly sealed metal containers under an inert gas such as argon.
