Talk:Saline water

2500 PPM
What does it mean by "in Colorado, water having up to 2,500 ppm of salt is used for irrigating crops." Is that a requirement from somewhere? Or is that just what's available?

Answer
Well, it would be sort of obvious to me that water up to 2,500 ppm of salt is usable because anything higher would make the plants die Gradster1 21:48, 6 January 2007 (UTC)

Where is it located?
Is this sea water? Is it our common Ocean? —Preceding unsigned comment added by 69.15.80.210 (talk) 15:44, 9 October 2007 (UTC)

Why
'''Normally, moderately or highly salinated water is of little use to humans. Humans cannot drink salinated water directly, nor is it suitable for irrigating crops.'''

Why can't humans drink salty water? We eat salty foods all the time. 207.179.157.81 (talk) 23:28, 23 June 2008 (UTC)


 * This may be weird but, I tried drinking salty water and nothing bad happened to me. 207.179.153.65 (talk) 19:37, 19 December 2008 (UTC)

Solubility
I was hoping to find an article on the solubility of salt in water, but don't know where to find it. Does H20 become more soluble at higher pressures (like in science fiction literature) or does it become less soluble? That is, if we increase the pressure but keep the temperature the same, can you mix in more salt, or is there a point where it precipitates or suddenly separates and comes out of solution? If anybody knows the answer, please post it here, or post a link where I can go to find out. There's bound to be a lot of studies on this.

Also, I wanted to read up on the electrical conductivity of salt mixed into water. If there is more salt, does it increase its electrical conductivity, or is there a point where electricity doesn't pass through? All of this may be obvious to you, but I went here to find out the answer, and couldn't get any farther. Dexter Nextnumber (talk) 08:03, 10 January 2013 (UTC)

Error
"The United States Geological Survey classifies saline water in three salinity categories. Salt concentration in slightly saline water is around 2,000 to 6,000 ppm (0.1-0.3%), in moderately saline water 7,000 to 15,000 ppm (0.3-1%) and in highly saline water 15,000 to 50,000 ppm (1-33.5%)."

If this is true then a concentration of salt in water between 6,001 to 6,999 ppm falls into no category. — Preceding unsigned comment added by 203.9.151.254 (talk) 05:12, 2 November 2013 (UTC)

Confusing
What is this trying to say? "Due to their proximity to the Atlantic Ocean, states near the coast make the most use of saline water. Almost 40% of all saline water use in 2000 occurred in California, Florida, and Maryland.[2]" Should it be, "Due to their proximity to the oceans, states near the coast make the most use of saline water." ? Or "Due to their proximity to the Atlantic Ocean, the eastern states near the coast make the most use of saline water." If so, it shouldn't abruptly mention California! Zipzip50 (talk) 08:05, 5 November 2013 (UTC) Thanks for the clarification. The US figures are very interesting. If anyone has similar figures for the rest of the world, that would make a nice addition to the article.Zipzip50 (talk) 07:38, 15 February 2014 (UTC)

WikiProject Food and drink?
Whoever added this to the Food and Drink project should put some info into the article tying it into that subject. The only things I can think of would be desalinization efforts and work being done to breed salt tolerant food plants. And fishing.Zipzip50 (talk) 07:55, 15 February 2014 (UTC)

Boiling temperature
The article has a great table for the effect on freezing temperature. Can you add a similar one for boiling? I’m sure it can be calculated by formulas somewhere on Wiki (like Boiling-point elevation ?), but I’d rather “read” the answer, than (unsurely) calculate.

NB: The web has told me 0.5°C rise for 29g (physics site), or 58g (diff site, but PhD author), of (NaCl) salt, per kilo water. MBG02 (talk) 17:34, 2 September 2018 (UTC)

Why. Again.
Why can't humans drink salty water?

Asked above in 2008. Not answered in this article. “Surrounded by water but not a drop to drink” (or, “nor any drop”). Why not! What happens?

Is this the article for the answer? MBG02 (talk) 17:40, 2 September 2018 (UTC)

Maximum salinity
Very confusing in this and all the related articles, such as the list of hypersaline bodies. The lead seems to indicate that even boiling water can only dissolve up to 28 grams of various salts per liter (or does it strictly refer to NaCl?), which has been duly adopted by someone as
 * "Brine (> 5% up to 26%–28% max)",

a line placed in the infoboxes of all the related articles. But as one looks at the actual salinity figures of the top hypersaline bodies, they reach higher, into the mid-thirties and even over 40. And those lakes are far from boiling! I don't believe it can be up to atmospheric pressure, either: the Dead Sea (34%) is some 430 m below sea level, but the lake in Ethiopia who's the No. 1, Gaet'ale Pond (43%), is above sea level, as are probably all others. And even below sea level elevations can hardly make up for a 25% rise of the "maximum" salinity level, or can't it?

So, what is the formula behind the "28% maximum salinity level", and why is it wrong? Arminden (talk) 08:52, 19 December 2022 (UTC)

Saline water → Salt water – Per WP:COMMONNAME based on the Google Ngrams. Rreagan007 (talk) 22:07, 15 August 2023 (UTC)
 * Oppose "Saltwater" also commonly refers to seawater - in fact, that's what I attribute to the term. It can also refer to brine. I would rather move Salt water (disambiguation) to Saltwater so a reader can choose which one they are actually looking for. ᴢxᴄᴠʙɴᴍ (ᴛ) 12:06, 16 August 2023 (UTC)
 * Oppose and move Salt water (disambiguation) to the base name since "salt water" can refer to any water that has salt but otherwise I'd have supported the move as I've never heard the term "Saline water" but its probably fine as natural disambiguation.  Crouch, Swale  ( talk ) 16:21, 20 August 2023 (UTC)
 * Comment: Note that the article says "saline water is saltier than brackish water, but less salty than brine". So the term seems to be restricted in its range of saltiness, and thus does not seem synonymous with "Salt water". —⁠ ⁠BarrelProof (talk) 23:06, 21 August 2023 (UTC)

w/w
Found this as an explanation of "w/w", but I don't see anything in WP to link to about it. May be worth a discussion somewhere on whether we should have something about that notation. Donald Albury 22:35, 21 August 2023 (UTC)
 * Thank you. I just added a definition at Mass fraction (chemistry) and commented at Talk:Mass fraction (chemistry). The definition I added is consistent with the source you cited. I found an existing redirect at and created new ones at  and . I found a redirect at  that redirected to what seems to be the wrong place  and redirected it to there as well. —⁠ ⁠BarrelProof (talk) 22:57, 21 August 2023 (UTC)
