Talk:Zinc chloride

message: Is zinc chloride really THIS soluble? Adding 432 grams of dry powder in 100 grams of water, and still say that it dissolves? Wim van Dorst July 8, 2005 19:43 (UTC).
:Yes, true, according to the Merck Index and the CRC Handbook.  If I get a chance I will check this, but I seem to recall reading something like, "Zinc chloride has the remarkable ability to dissolve in only ...."  The solubility in boiling water is even more remarkable, 614g per 100g H2O!  And ZnBr2 has similar solubility.  Walkerma 19:50, 11 July 2005 (UTC)
thread_title:  Solubility 

message: This makes no sense (a mix of topics) and has no citations: "Typically this flux was prepared by dissolving zinc foil in dilute hydrochloric acid until the liquid ceased to evolve hydrogen, for this reason such flux was known as killed spirits. because of its corrosive nature it is not a suitable flux for situations where any residue cannot be cleaned totally away, such as electronic work. This property also leads to its use in the manufacture of magnesia cements for dental fillings and certain mouthwashes as an active ingredient. "
:Yes, this was probably added by someone passing through who was familiar with the use.  It seems plausible.  Do you know anything about this topic, enough to rewrite it with a citation?  Or should we just delete it?  When I originally wrote the article, my source only stated that it was used as a flux - no details. Walkerma 20:59, 6 November 2006 (UTC)
replies: text:  This property also leads to its use in the manufacture of magnesia cements for dental fillings and certain mouthwashes as an active ingredient. does not sound plausible - which property exactly leads to its use in mouthwashes?! I suggest to delete it (well, keep it here on the discussion page) until someone comes with a source and it can be rewritten properly. Iridos 22:42, 26 April 2007 (UTC)

message: I was missing this data on toxicity in the article. The LD-50 value gives you a rough estimate of the amounts when a substance will be toxic (like, if you're factor 100 or 1000 away from it it should be non-toxic for a single exposure). 
Not sure, if all of those should be entered, or only some of them, so I put them here for discussion first. They should probably go in the table in some way.
LD50:
* ORL-RAT LD50 350 mg/kg
* IPR-RAT LD50 58 mg/kg
* ORL-MUS LD50 350 mg/kg
* IPR-MUS LD50 24 mg/kg
* SCU-MUS LD50 330 mg/kg
* ORL-GPG LD50 200 mg/kg

replies: text: ZnCl2 does not have particularly interesting toxicology.  Zn2+ of course does being so pervasive in enzymology and in natural waters etc.   But most of the effects that you will allude to arise from Zn2+, fairly independent of the counter anion.  So by all means write an article about the biomedical chem of Zn2+!  Great project for you and WE-chem.  But it might save your time and that of readers if the information were consolidated, otherwise one would need to include very similar information into dozens of articles describing Zn2+ salts (thousands are known).  And each one of these individualised safety blurbs (on the sulfate, bromide, chloride, iodide, carbonate, mixed anion...) would be subjected to independent editing by well meaning individuals who rarely understand even introductory coordination chemistry or the difference between various hydrates and gegenions and the difference between solid state structures and solution structures.  But maybe you have some deeper insights and we look forward to reading them.  There are four crystalline modifications of anhydrous ZnCl2 and several hydrates.  Each has its own MSDS - so how do you decide which one gets the priority???  Ditto for many of the zinc salts. --Smokefoot 12:58, 27 April 2007 (UTC)
thread_title: Toxicity

message: The fact that zinc chloride dissolves very well does not imply that it always dissociates. It is not a salt like but a rather covalent material. On concentrated solutions (or molten hydrates if you prefer) FTIR and EXAFS studies show various Zn-Clx-H2O complexes in existence.   Yamaguchi et al J Phys Chem 1989, 93, 2620-25.

thread_title: dissociation

message: I have reorganized the article by adding a new section for reactions. This is IMO still only a B class article as there is much still missing- e.g. ZnCl2 chemistry in dry batteries, complexes to name a few areas. It still needs more rationalisation - theres a lot of good stuff here but it doesn't flow--Axiosaurus (talk) 12:43, 12 January 2009 (UTC)

message: Does Febreeze actually contain zinc chloride? 
How does it help "eliminating odour" as febreeze supposedly does?
And how does it have anything to do with "affinity to fabric" or "zinc chloride ability to dissolve natural fibre"?  —Preceding unsigned comment added by 173.32.73.90 (talk) 06:20, 9 June 2009 (UTC)
thread_title:  Textile Section: Zinc chloride and febreeze 

message: According to the article on Zinc-Carbon Batteries, this is used in them. Yet, this article makes no mention of that in its "Applications" section. I'd fix it myself, but you're supposed to cite outside references, and I'm too lazy to find one myself. 63.3.9.1 (talk) 23:45, 17 February 2010 (UTC)
thread_title:  Use in batteries 

message: This section misleads zinc chloride as a viable cancer treatment.  Both citationshttp://www.dermnetnz.org/treatments/escharotics.htmlhttp://www.ncbi.nlm.nih.gov/pubmed/12472348 in the article are dubious about zinc chloride as an effective cancer treatment. This section should either be deleted or expanded upon zinc chloride as a questionable alternative medicine cancer treatment.  — Preceding unsigned comment added by 76.219.105.65 (talk) 06:08, 9 November 2014 (UTC)
