Sodium metal(Na metal)

Product Information

Sodium is a soft, silvery coloured metal which, like other members of the alkali group of metals, is extremely reactive. As for the other members of the group, it can be prepared by electrolysis of the fused halide or hydroxide. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth’s crust. primarily as the carbonate, chloride or nitrate. Molten sodium is used as a heat exchanger in certain types of nuclear reactors and as a reagent in the chemicals industry. Some of the sodium salts e.g. NaCl and NaCO₃) are more important than the metal itself due to the variety of applications for which they can be used. Sodium is an essential element for all living species, including humans, although there is an element of controversy concerning the amount required. An average human body contains around 100 gms of sodium which are lost in various ways and have to be replenished. The average human consumes approximately 10 gms of salt per day although only around 3 gms are actually needed and an excess can contribute to high blood pressure. Sodium performs several functions within the body including the regulation of the water content in the blood and tissue and the transmission of electrical impulses. Metallic sodium is generally less reactive than potassium and more reactive than lithium.Sodium metal is highly reducing, with the standard reduction potential for the Na+/Na couple being −2.71 volts,[16] though potassium and lithium have even more negative potentials.Liquid sodium is a popular coolants for the fast breeder reactor.

Applications of Sodium metal

Sodium forms alloys with many metals, such as potassium, calcium, lead, and the group 11 and 12 elements. Sodium and potassium form KNa2 and NaK. NaK is 40–90% potassium and it is liquid at ambient temperature. It is an excellent thermal and electrical conductor. Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl₂ and ternary mixture NaCl-CaCl₂-BaCl₂. Calcium is only partially miscible with sodium, and the 1-2% of it dissolved in the sodium obtained from said mixtures can be precipitated by cooling to 120 °C and filtering.

In a liquid state, sodium is completely miscible with lead. There are several methods to make sodium-lead alloys. One is to melt them together and another is to deposit sodium electrolytically on molten lead cathodes. NaPb_3, NaPb, Na₉Pb₄, Na₅Pb₂, and Na₁₅Pb₄ are some of the known sodium-lead alloys. Sodium also forms alloys with gold (NaAu₂) and silver (NaAg₂). Group 12 metals (zinc, cadmium and mercury) are known to make alloys with sodium. NaZn₁₃ and NaCd₂ are alloys of zinc and cadmium. Sodium and mercury form NaHg, NaHg₄, NaHg₂, Na₃Hg_2, and Na₃Hg.

Metallic sodium is used mainly for the production of sodium borohydride, sodium azide, indigo, and triphenylphosphine. A once-common use was the making of tetraethyllead and titanium metal; because of the move away from TEL and new titanium production methods, the production of sodium declined after 1970.Sodium is also used as an alloying metal, an anti-scaling agent,[64] and as a reducing agent for metals when other materials are ineffective. Note the free element is not used as a scaling agent, ions in the water are exchanged for sodium ions. Sodium plasma ("vapor") lamps are often used for street lighting in cities, shedding light that ranges from yellow-orange to peach as the pressure increases.By itself or with potassium, sodium is a desiccant; it gives an intense blue coloration with benzophenone when the desiccate is dry
