what are it's uses ?
Anti-icing and de-icing and as a preservative
Sodium
 Sodium chloride is extensively used for anti-icing and de-icing and as a preservative; examples of the uses of sodium bicarbonate include baking, as a raising agent, and sodablasting.
why alkali metals have low melting and boiling points It is because metal atoms are held together by the electromagnetic attraction from the positive ions to the delocalised electrons. what are they ? They are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. give some examples of them ? Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). what is the pricing of the first mentioned metal ? After the 2007 financial crisis, major suppliers, such as Sociedad Química y Minera (SQM), dropped lithium carbonate pricing by 20% and it rose in 2012. is it used for air purification ? Yes, lithium hydroxide and lithium peroxide are the salts most used in it. the above company who dropped their prices where is it located ? Its headquartered in Santiago. what other products it offers ? Plant nutrients, iodine and industrial chemicals is the second mentioned metal above is safe ? No, it forms flammable hydrogen and caustic sodium hydroxide on contact with water; ingestion and contact with moisture on skin, eyes or mucous membranes can cause severe burns.

Sodium [SEP] Uses
Though metallic sodium has some important uses, the major applications for sodium use compounds; millions of tons of sodium chloride, hydroxide, and carbonate are produced annually. Sodium chloride is extensively used for anti-icing and de-icing and as a preservative; examples of the uses of sodium bicarbonate include baking, as a raising agent, and sodablasting. Along with potassium, many important medicines have sodium added to improve their bioavailability; though potassium is the better ion in most cases, sodium is chosen for its lower price and atomic weight. Sodium hydride is used as a base for various reactions (such as the aldol reaction) in organic chemistry, and as a reducing agent in inorganic chemistry.
