Non soluble portion of common salt

see under a microscope pag 36-41 http://coseinteressanti.altervista.org/chemistry.pdf what is it ? —Preceding unsigned comment added by 79.30.228.175 (talk) 20:15, 13 December 2008 (UTC)[reply]


The first sentence of miscellaneous uses

This sentence

"Sodium chloride is heavily used, so even relatively minor applications can consume massive quantities. "

is a terrible sentence. Someone please write this better!


Brine

HI Can anyone tell me how many grams of salt i would need to add to 1 litre of water to make it brine, i need it to not freeze for pressure cleaning freezer floors/ freezer runs at about -35 deg cel (121.45.34.154 (talk) 07:12, 20 April 2009 (UTC))[reply]

As much as can dissolve. --Chemicalinterest (talk) 00:13, 8 September 2010 (UTC)[reply]

Error in Chemical Equation?

Doesn't chloride come in 2 molecules? If so, wouldn't the chemical equation NaCl be incorrect? To balance this out, wouldn't the correct equation be 2NaCl? —Preceding unsigned comment added by Seg162 (talk • contribs) 14:43, 24 January 2010 (UTC)[reply]

Hi. Thanks for your comment. I don't see any problem in the formulas of the example "2 NaCl + 2 H2O → Cl2 + H2 + 2 NaOH". Are you referring to the equation of the compound itself? If so, this is incorrect. Chlorine is usually diatomic if it is a pure compound (Cl2), but this element can also bond with other elements and this does not always result in two chlorine atoms. NaCl is the correct form of the equation. Sodium has a positive charge and chlorine has a negative charge, making NaCl (without the 2 coefficient) a stable compound. [[1]] Hope this helps.

Alternative Names?

To me it seems that the alternative names section is completely not needed. There are already other common names at the top in the infobox and many of the lower alternative names are obscure (not English) or rarely used (sodium monochloride?, chloride of sodium?). Hopefully this article is improved with the top importance rating! —Preceding unsigned comment added by 134.139.219.163 (talk) 05:19, 22 March 2010 (UTC)[reply]

You can edit it if you really think it needs improvement. --Chemicalinterest (talk) 00:12, 8 September 2010 (UTC)[reply]

Effect of salt intake on blood pressure

"In humans, a high-salt intake has long been known to generally raise blood pressure." Apparently it's not quite so clear.

study shows that "The magnitude of the effect in Caucasians with normal blood pressure does not warrant a general recommendation to reduce sodium intake."

This study explains how salt intake affects blood pressure in some people who are "salt sensitive", but has little effect in other people.

It sounds like the issue is not so clear-cut, and the issue of salt intake is treated differently outside of North America. Could someone who has a good knowledge of this topic make that section clearer? In the meantime I will change "known" to "suspected". Tenbergen (talk) 21:27, 31 July 2010 (UTC)[reply]

I fear we are picking a couple of small studies which go against a massive body of evidence - I suggest we refer out to Salt and cardiovascular disease WKChris (talk) 20:22, 13 August 2013 (UTC)[reply]

I changed your reference in the article. Please try using more reliable and non-commercial links. Google books may provide such. Materialscientist (talk) 00:45, 27 September 2010 (UTC)[reply]
Thank you for finding a "better" source. But I think it would be preferable to also give an explicit room-temperature value. And can you edit the infobox?-71.174.182.205 (talk) 02:18, 29 September 2010 (UTC)[reply]

Irrelevant images

just though id question the relevance of two images in the article, clouds above the pacific, and the metal extinguisher :P 70.55.107.81 (talk) 05:47, 7 December 2010 (UTC)[reply]

Well, they are kind of mentioned in the text. Materialscientist (talk) 05:58, 7 December 2010 (UTC)[reply]

Molecular formula

Why does the molecular formula show ClNa instead of NaCl? Can someone edit that? Vmelkon (talk) 19:27, 21 April 2011 (UTC)[reply]

Either is correct, but NaCl is more common, so I switched to that. -- Ed (Edgar181) 19:41, 21 April 2011 (UTC)[reply]

Density units

The units for density in the sidebar should be checked.--76.254.46.57 (talk) 04:51, 27 February 2012 (UTC)[reply]

Wait, nevermind. Disregard.--76.254.46.57 (talk) 04:52, 27 February 2012 (UTC)[reply]
Hold on, they do look wrong. (g dm/L is equivalent to g dm dm-3 which simplifies down to g dm-2, which is wrong. Is the number OK? — Preceding unsigned comment added by GKFX (talk • contribs) 13:56, 3 January 2014 (UTC)[reply]

metal aquo complex wrong?

it says in the formula that Natrium ions are surrounded by 8 water, but isn't this actually 6 water molecules for all elements in periods 3 and 4? — Preceding unsigned comment added by 212.107.151.249 (talk) 15:04, 17 March 2013 (UTC)[reply]

Merge Halite into this article

Halite is too similar to sodium chloride. The only difference between them is that halite is a natually occuring impure form of sodium chloride. Blackbombchu (talk) 18:58, 7 January 2014 (UTC)[reply]

I don't get this argument at all. By that logic, we'd redirect Diamond and Graphite to Carbon. Mogism (talk) 21:42, 8 January 2014 (UTC)[reply]
I agree, no merge. Sodium chloride (inorganic substance), halite (valid mineral) and rock salt (rock type) are different things, sorry. Diamond, lonsdaleite, graphite might have been redirected to carbon (element) during the first Wikipedia year, and halite and rock salt might have been redirected to sodium chloride, as well. But these were compromises. --Chris.urs-o (talk) 08:18, 22 January 2014 (UTC)[reply]
No merge. The sodium chloride, halite, and salt articles have different focus, and are large enough to stand on their own. However, some tweaking and consolidation of content, plus better cross-referencing, might strengthen all three articles. Reify-tech (talk) 14:18, 23 January 2014 (UTC)[reply]

Don't merge, a merged article would only add unnecessary confusion. — Preceding unsigned comment added by 74.5.131.62 (talk) 01:38, 25 January 2014 (UTC)[reply]


Don't merge. Halite is a topic on its own. Cross references are appropriate. — Preceding unsigned comment added by 108.90.8.231 (talk) 01:44, 4 February 2014 (UTC)[reply]

Close - no support for merger. Vsmith (talk) 00:28, 2 March 2014 (UTC)[reply]

Non-SI units

I see this page is tagged for non-SI units, but I cannot find any in the article; what is it that needs attention? StephenTX (talk) 03:44, 4 February 2014 (UTC)[reply]

Electrolysis end products

I understand that the "same reactants" can yield different results: ethanol + sulfuric acid = {ethylene, diethyl ether} depending on temperature. But the entries for sodium hypochlorite sodium chlorate and sodium perchlorate all pretty much say that they're created the same way. Can someone knowledgeable on this topic put in the differentiating conditions? — Preceding unsigned comment added by 68.32.223.91 (talk) 02:13, 29 September 2014 (UTC) — Preceding unsigned comment added by 68.32.223.91 (talk)

More information to add to the article

Is 23.31 wt% the saturated concentration of sodium chloride at -21.12°C? What's the temperature below which sodium chloride precipitates as the hydrated salt? Does the solubility curve of sodium chloride bend at the dividing temperature between one form precipitating and the other form precipitating? Blackbombchu (talk) 19:13, 11 May 2015 (UTC)[reply]

what Na is sodium chloride

I'm trying to make a periodic table of elements and a want to break down type of salt. I can't find any Na= sodium.... on this sight so put that on. Thank you.Marcjackie12345 (talk) 19:59, 6 June 2015 (UTC)[reply]

Na leads to a disambiguation page, which clearly lists Sodium as one meaning. Please explain more clearly what you're trying to do. Reify-tech (talk) 20:07, 6 June 2015 (UTC)[reply]

under Biological Functions

Which is it? Is it more dietary salt, or less dietary salt, that attenuates (i.e., reduces) nitric oxide production. While an assumption may be in force here, it might be better just to spell it out to avoid any ambiguity. JimScott (talk) 20:11, 21 July 2015 (UTC)[reply]

Salt vs sodium chloride

This article is using salt and sodium chloride interchangeably, there's no obvious consistency. Is there a standard on which to use? -- 139.216.128.154 (talk) 06:26, 26 June 2016 (UTC)[reply]

"Iodine" link in image description

Image description for the picture of salt flats in the 'Biological functions' section has a link that refers to iodine in the wiki commons(https://commons.wikimedia.org/wiki/Iodine), NOT to the wikipedia page for "Iodine" (https://en.wikipedia.org/wiki/iodine) as I believe it should be. It was a featured image in 2007, and I can't figure out how to make an edit (I believe it's locked? I can't edit the description from the Sodium chloride page). — Preceding unsigned comment added by Charlielovesyou (talk • contribs) 04:58, 26 September 2016 (UTC)[reply]

Medical benefits section needed

Sodium chloride has a range of medical benefits and different uses. For example, it can be used in a nebulizer as an inhalant (see https://en.wikipedia.org/wiki/List_of_medical_inhalants). It can also be used in a spray formulation for relieving nasal congestion and hay fever symptoms. I'm not an expert so I cannot create this section myself. — Preceding unsigned comment added by 188.172.219.68 (talk) 16:40, 26 March 2017 (UTC)[reply]

Sodium Chloride Solubility in water

The page lists the solubility in water @ 359 g/L

This is incorrect. 359 g/L implies 359 g of salt into a final volume of 1L The literature lists the sol as 357 g in 1000 parts water. This implies adding 357 g to 1000 grams of water. The final volume of this solution will be closer to 1200 mL108.171.130.188 (talk) 12:53, 20 June 2017 (UTC)[reply]

Undiscussed cut and paste move and merge

On June 7th user Vorpzn made a cut and paste move and merge from Salt to Sodium chloride. This sort of move is not allowed since it disrupts editing history, and in any event this is a major change that should have had consensus before being enacted. My understanding is that the Salt article is meant to discuss edible salt, which is not pure sodium chloride, while Sodium chloride is a more chemically focused article. Regardless of whether or not there should be two articles, this was not the correct way to merge them together. --Mikaka (talk) 03:51, 29 June 2017 (UTC)[reply]

It also substantially changed the scope of the Vital Article for Salt. See WT:Vital articles#Salt for discussion. Jclemens (talk) 05:55, 9 August 2017 (UTC)[reply]

Chlorine valence in the mentioned unusual stoichiometries of salt

In the mentioned unexpected stable stoichiometries, what is the valence of chlorine, other than 1?--5.2.200.163 (talk) 14:53, 6 August 2018 (UTC)[reply]

Colloquial cluster fluoridism

Sodium chloride /ˌsoʊdiəm ˈklɔːraɪd/, also known as salt (though sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms.

The italic was my recent addition, but then I noticed that both instances of salt link to the salt chemistry page. I don't wish to resolve this myself.

I do think that it's bad pedagogy to let the "also known as" stand naked as if 'salt' was not a deeply problematic synonym.

Perhaps the solution is to say "also known as salt when packaged as refined table salt" or something like that. — MaxEnt 02:06, 5 October 2018 (UTC)[reply]
