Sodium has a special place in inorganic chemistry and is one of the most volatile metals in the periodic table. With symbol Na (Latin natrium) and atomic number, 11 Sodium is a chemical element which is a silvery-white, soft, highly reactive in nature. Being in group 1 of the famous periodic table Sodium is an alkali metal, hence it readily donates an electron by creating a positively charged atom i.e. Na+ cation. The free metal does not exist in nature but can be prepared from different compounds. Sodium (Na) is the 6th most abundant element in the Earth’s crust and exists in various minerals such as sodalite, feldspars, and rock salt (NaCl). Most of the salts of sodium are highly water-soluble. But here we are not going to talk about the core chemistry anymore as there is something more important to know about Sodium.
Requirement Of Sodium:
Human Body does require various minerals in a limited and a controlled amount to meet the various functions and activities. 1500 mg of sodium each day is must for Healthy adult and1000-1500 mg of sodium for healthy children. The limit should not exceed 2300 mg of sodium /day in case of adults. In the case of Athletes, a higher amount of sodium is required because it is lost in the sweat.
Best Sources Of Sodium:
To fulfill the requirements of Sodium we need to go for dietary sources and the most common is common salt. In common salt (NaCl) nearly 40% sodium is present. Other dietary sources are sausage, processed meat, bacon, ham and canned vegetables and soups. Fast foods or the Junk foods have a very high content of sodium. Added forms include monosodium glutamate, sodium nitrite, baking soda, sodium saccharin and sodium benzoate. These are mostly found in onion salt, soy sauce, garlic salt etc.
