Argon Reduction

Chemical Formula: Ar
Present as: Inert Gas (dissolved)

Argon is a chemical element with symbol Ar and atomic number 18. Argon is the third most abundant gas in the Earth’s atmosphere, more than twice as abundant as water vapor, 23 times as abundant as carbon dioxide, and more than 500 times as abundant as neon. Argon is also the most abundant noble gas in Earth’s crust.
Nearly all of the argon in Earth’s atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in the Earth’s crust. In the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas.
The name “argon” is derived from the Greek word ἀργόν, neuter singular form of ἀργός meaning “lazy” or “inactive”, as a reference to the fact that the element undergoes almost no chemical reactions.
It is used in welding and other applications that require an inert gas. Argon has limited solubility in water and can be removed by a variety of degasification techniques.
