Where is sodium found?
The most important sodium salts found in nature are sodium chloride (halite or rock salt), sodium carbonate (trona or soda), sodium borate (borax), sodium nitrate and sodium sulfate. Sodium salts are found in seawater (1.05%), salty lakes, alkaline lakes and mineral spring water.
What is the origin of sodium?
A soft, silvery white and highly reactive metal, sodium was first isolated in 1807 by Humphry Davy during the process of electrolysis of sodium hydroxide. It’s symbol and name derive from the Latin Natrium or Arabicnatrun and the Egyptian word ntry (Natrun), all of which refer to soda or sodium carbonate.
How do you turn salt into sodium?
To convert sodium to salt, you simply multiply by 2.5. So, if a meal had 1000mg of sodium in it, that would be 2500mg of salt. Except since we typically refer to salt in grams, it would be 2.5g of salt. Vice versa, to convert salt to sodium, you divide by 2.5.

Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. The corrosion of solid sodium by oxygen also is accelerated by the presence of small amounts of impurities in the sodium.
Is salt and sodium the same thing?
The words “table salt” and “sodium” are often used interchangeably, but they do not mean the same thing. Table salt (also known by its chemical name, sodium chloride) is a crystal-like compound that is abundant in nature. Sodium is a mineral, and one of the chemical elements found in salt.
What is the most explosive element?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
