Sodium density

The relative density of sodium is 0.97 at 20°C (68°F). Sodium is a chemical element whose known symbol is Na. Its atomic number is 11 and its atomic mass is 22.9898. Sodium is ranked sixth in abundance among the rest of the elements in the earth’s crust (which in its combined forms contains 2.83% sodium).

Sodium density

Sodium (after chlorine), becomes the number two element, with greater abundance in solution than sea water, being the most important sodium salts those found in nature, and which are known as :

• Sodium chloride: which is rock salt.
• Sodium carbonate: what are soda and trona.
• Sodium borate: what is borax?
• Sodium nitrate: which is Chilean nitrate.
• Sodium sulphate.

Where are the sodium salts found?

These sodium salts are found in:

• salt lakes
• Sea water
• alkaline lakes
• mineral springs

Compared to the density of sodium, it is 0.97 when the temperature is 20°C. It is worth emphasizing that in terms of commerciality, sodium, among the alkali metals, is the one that has the greatest importance.

sodium reactions

• In the reactions of sodium, we find that with water, sodium has a very rapid reaction; as with ice and also snow (because this produces sodium hydroxide and hydrogen).
• When sodium is exposed to air and freshly cut, it tends to lose its silvery appearance and its color changes to a dull gray.

Other reactions of sodium

Sodium does not react with nitrogen even at extremely high temperatures, however, it can react with ammonia (resulting in the formation of sodium amide).

It is extremely difficult for sodium to react with carbon. Even when this is the case with halogens. Sodium chloride is produced by the reaction of sodium with various metal halides, with which the metal is also formed.

The effects of sodium on health

Undoubtedly, the first thing we use in sodium is in food, as it is a component of it in its regular salt form. It is necessary for humans to maintain a balance between physical fluid systems. Sodium is necessary for the functioning of nerves and muscles. However, it should be mentioned that consuming too much sodium could cause kidney damage. In addition, it becomes a possible cause for the increase in blood pressure.

Sodium and the environment

Sodium cannot move as it is in its solid form, although it is very easily absorbed by moisture. After becoming liquid in its sodium hydroxide form, it quickly seeps into the ground. This gives the possibility that water supplies can be contaminated.
