Occurrence[edit]

I expanded the section to include rough statement comparing the amount of sodium chloride in the Earth's crust, atmosphere, and ocean. Good places to look to refine and validate these estimates are listed below. There one can see that The crust and ocean contain comparable amounts of sodium, but most of the crust's sodium is in minerals less soluble than halite, leaving the crust less than less 1/10 as much chlorine as the ocean. Less seems to be known about how much chlorine is in the core and mantle, but probably not much.CharlesHBennett (talk) 12:54, 16 October 2022 (UTC)[reply]

It would be good to have this section expanded

The geo-chemical processes that created salt,
Where does salt come from that we use today (mines, evaporation, etc.)

Oceans do not contain sodium chloride[edit]

Re just deleted: "Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms." Maybe I am being semantic, but those statements are false. Oceans and cells have lots of Na⁺ and Cl⁻, but they dont have NaCl. --Smokefoot (talk) 19:01, 4 April 2024 (UTC)[reply]

Oh I definitely think you're being too pedantic. A saline solution is notated as NaCl(aq) by default.--Jasper Deng (talk) 19:04, 4 April 2024 (UTC)[reply]

It would be useful if people understood that saline solutions do not contain NaCl. But you might be correct. --Smokefoot (talk) 19:13, 4 April 2024 (UTC)[reply]
