Buntawit Posted September 28, 2011 Share Posted September 28, 2011 To day, My aunt he's told me to show something, and he lift a breaker 100 mL with yellow solution and he heat it in few minute and he put iron nail 4" in it and wait for 3-5 Minute then he take iron nail up form yellow solution and clean it with water then he can break it ? I can confirm the iron nail is real My question : What solution be !? Aqua regia ? I think it is base on science please help me Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted September 29, 2011 Share Posted September 29, 2011 Sounds like aqua regia or possibly nitric acid. Given how quickly it corroded the nail, I'm going with aqua regia. Link to comment Share on other sites More sharing options...
Buntawit Posted September 29, 2011 Author Share Posted September 29, 2011 It use about 3-5 Minute , Do you think aqua regia can change structure of iron nails, it not only corrode ? Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted September 29, 2011 Share Posted September 29, 2011 I'm not 100%, but I would think that the nitric acid in the aqua regia is oxidising the iron, which then reacts with HCl to form the iron chloride salt. Link to comment Share on other sites More sharing options...
Buntawit Posted September 29, 2011 Author Share Posted September 29, 2011 I think too, but I test with my aqua regia with 3:1 HCl : HNO3 Commercial grade and wait 24 Hr For Emitted gas It's corrode but I can't break or crack Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted September 29, 2011 Share Posted September 29, 2011 Could be that the nail was a different composition. Link to comment Share on other sites More sharing options...
Buntawit Posted September 29, 2011 Author Share Posted September 29, 2011 May be, But it's standard commercial nails I hope I'll get answer for this experimental soon thank you so much Hypervalent_iodine Link to comment Share on other sites More sharing options...

hypervalent_iodine Posted October 1, 2011 Share Posted October 1, 2011 (edited) To be honest, I'm not really experienced with the stuff. According to the wiki page, it's yellow or red, so I guess you're okay. Edited October 1, 2011 by hypervalent_iodine Link to comment Share on other sites More sharing options...

mississippichem Posted October 2, 2011 Share Posted October 2, 2011 I've used it to clean ridiculously dirty glassware and it is usually red when fresh and yellows over time. Make it in small amounts and use it fresh. Link to comment Share on other sites More sharing options...
