Talk:Magnesium chloride

message: I propose that the second word in the title be written in lowercase because of the following:
#As far as I have ever seen, compounds aren't capitalized, especially not the anion in an ionic compound
#The wikipedia manual of style says this is the preferred/accepted way
#None of the other members of the Magnesium compounds category have capitalized anion names (I haven't checked other compound categories)

message: This article repeatedly refers to "Liquid magnesium chloride" (in the de-icing section) when it means "a magnesium chloride solution" (i.e. in water)?  Since this phrase is not that much longer, can we replace it?  It's much more technically accurate--we don't want people running around thinking this is a liquid--rather, it's a solid salt that is dissolved in water.  Cazort (talk) 18:09, 15 March 2009 (UTC)

replies: text: Would someone please fix that?  I'm not sure of the correct terminology, but "liquid magnesium chloride" would be a molten salt.

message: Looking for information on bittern, I got redirected to this page. No mention of the word bittern is made on this page, however. Mention that the word "bittern" is used would be useful as would a description of how the two terms differ, whether they are completely equivalent or if their scopes of use differ in some respect.

message: Magnesium chloride is used for low-temperature de-icing  of highways, sidewalks, and parking lots. When highways are treacherous due to icy conditions, magnesium chloride helps to prevent the ice bond, allowing snow plows to clear the roads more efficiently. 
Magnesium chloride is used in three ways for pavement ice control: Anti-icing, when maintenance professionals spread it onto roads before a snow storm to prevent snow from sticking and ice from forming; pre-wetting, which means a liquid formulation of magnesium chloride is sprayed directly onto salt as it is being spread onto roadway pavement, wetting the salt so that it sticks to the road; and pre-treating, when magnesium chloride and salt are mixed together before they are loaded onto trucks and spread onto paved roads.
 
While it is generally accepted that ongoing use of any de-icer (ice melter) will eventually contribute to some degradation of the concrete surface to which it is applied, some de-icers are gentler on concrete than others.  Conflicting information in regards to magnesium chloride- and calcium chloride-based liquid de-icers have left many unsure which choice is best-suited for their needs.
Past studies have often utilized high temperatures to accelerate the impact to concrete. By setting parameters that more closely represent real-world de-icing conditions, Purdue University measured the impact of magnesium chloride and calcium chloride to concrete. Their study concluded that calcium chloride damages concrete twice as fast as magnesium chloride does*. (*Jain, J., Olek, J., Janusz, A., and Jozwiak-Niedzwiedzka, D., "Effects of Deicing Salt Solutions on Physical Properties of Pavement Concretes", Transportation Research Record: Journal of the Transportation Research Board, No. 2290, Transportation Research Board of the National Academies, Washington, D.C., 2012, pp. 69-75. DOI: 10.3141/2290-09)
NOTES/REASON FOR RECOMMENDATION ABOVE: THE CURRENT COPY UNDER ICE CONTROL FOCUSES ON CLAIMS OF UNDOCUMENTED DAMAGE BY MAG CHLORIDE TO UTILITY POLES AND INSULATORS. THERE IS NO SOURCE CITED TO SUPPORT THESE CLAIMS. IT ALSO TALKS ABOUT CORROSIVE DAMAGE TO "VEHICLE COMPONENTS," AND THE CITATION AGAIN DOES NOT SUPPORT THIS CLAIM. IF YOU GO TO THE ARTICLE IN HEAVY-DUTY TRUCKING CITED HERE, IT DOES NOT SUPPORT THE CLAIM. THE TRUCKING INDUSTRY AND THIS TRADE PUBLICATION HAVE, HOWEVER, FOR YEARS BLAMED MAG CHLORIDE FOR CORRODING TRUCK PARTS WITH NO PROOF. SIMPLY WASHING VEHICLES AFTER DRIVING ON TREATED ROADWAYS WILL PREVENT ANY MAJOR CORROSION, WHICH IS A SMALL PRICE TO PAY FOR UNDENIABLY SAFER ROADS. MAG CHLORIDE IS MOST COMMONLY USED TO CONTROL DUST AND STABILIZE GRAVEL ROADS AND SECOND-MOST COMMONLY USED TO DE-ICE ROADWAYS. THE CONTENT SHOULD REFLECT THAT. COMMENTS WELCOME.

message: Recently (March 2013), someone added a claim that magnesium chloride corrodes auto body parts and paint finishes, citing a post on an auto body shop's blog as evidence to support the claim. There is no evidence that magnesium chloride used as a dust control agent causes any adverse impact on vehicles, and an auto body shop blog is hardly a credible source for proof of chemical attack to paint.  — Preceding unsigned comment added by 64.151.4.23 (talk) 19:48, 12 March 2013 (UTC)

message: Under ice control, you CAN NOT say "ice bond." As a chemist, there is no such thing. This was clearly written by someone with a faulty understanding of chemistry or whose first language is not English. This should be a high priority edit. I'd change it myself, but I have no idea if the more accurate way of saying it is factually correct or not. Science Is My Life (talk) 11:36, 16 April 2021 (UTC)
