economic use of sodium

In the manufacture of sodium peroxide, sodamide, sodium cyanide etc. About 50 per cent of sodium extracted is used in the manufacture of tetraethyl lead (C 2 H 5 ) 4 Pb), which is used as anti-knock agent in petrol. For producing amalgams and a..

Lithium - For refining copper and nickel. For producing thermo nuclear energy for propelling rockets and guided missiles. For the manufacture of various alloys such as lithium lead alloy, lithium aluminium alloy etc. Lithium and its compounds are used as reagents in a number of organic sy..

Two molecules of alkyl halides (same or different) react with metallic sodium in the presence of ether to form alkanes. This reaction is called Wurtz reaction and is used to prepare symmetrical alkanes...

The common name of sodium nitrate is "Chile salt Petre". It is found in large quantity in Chile in South America. It can be prepared by treating the oxide, hydroxide, carbonate or hydrogen carbonate salts of sodium with nitric acid. It is a colorless crystalline solid, highly s..

In anhydrous form, sodium carbonate is described by the chemical formula Na 2 CO 3 . In crystalline state sodium carbonate exists as Na 2 CO 3 .10H 2 O (decahydrate) and is called washing soda. It is a white crystalline solid, which loses water (effloresces) to dry air to yield..

When a small piece of sodium metal is dropped into alcohol, hydrogen is liberated. This is accompanied by effervescence. In this test, the alcohol used must be free from moisture. This is because water reacts with sodium in the same way as alcohol, liberating hydrog..

This method is used in the laboratory to obtain benzene. Sodium benzoate is heated with soda-lime and when it gets decarboxylated (removal of carbon dioxide) benzene is obtained. sodium benzoate sodalime ..

A spray of sodium hydrogen carbonate is dispersed over the fires. It decomposes to give carbon dioxide, which puts out the fire. The sodium carbonate produced also helps by forming a layer over the burning object. The types of fire extinguishers mentioned above are not effecti..

A small piece of sodium is heated gently in an ignition tube till the sodium melts. About 50 to 60 mg of the organic compound is added to this and the tube heated strongly for 2-3 minutes to fuse the material inside it. After cooling, the tube is carefully broken in a china dis..
