Reaction between Sodium metal and Chlorine gas to form table salt also known as Sodium Chloride

Sodium chloride has two major components: sodium and chlorine. On their own, both elements sodium and chlorine are pretty reactive and dangerous, Sodium metal can explode when it comes in contact with water and Chlorine is a dangerous gas used as a weapon in word war I. However when they are combined together they can form the table salt.

Reaction between Sodium metal and Chlorine gas to form table salt also known as Sodium Chloride

Sodium metal

Sodium metal is actually quite shiny, but will quickly react with air and moisture and forms a white coating. The sodium metal is dripped off mineral oil where it was stored in, and then a small piece is cutted of to use it in the reaction.

Chlorine gas

To produce Chlorine gas, chlorine pool pellets are poured with hydrochloric acid inside an Erlenmeyer, and they react to produce chlorine gas. This gas has a greenish yellow colour. The top of the Erlenmeyer is blocked, so the chlorine gas is forced to go into a hose. The hose leads into a larger flask.

Product of the reaction

Inside the larger flask containing Chlorine gas, a small pellet of sodium is dropped. A little amount of water should be added to start the reaction.

White cloudiness appears inside the flask, a suspension of small particles of sodium chloride disposed on the flask’s walls. When the cloud of sodium chloride has dissipated, it’s easier to see a lot of the white sodium chloride around the flask. Unfortunately, the Sodium is highly contaminated, so the obtained Sodium Chloride in not pure. Although this product look nice white and clean I still highly advise that you don’t sprinkle this on to your food.
