Ice_Phoenix87 Posted February 20, 2004 Share Posted February 20, 2004 i put a egg in a dilute acid, what is happening? is it desolving the calcium in the shell and turning it into hydrogen oxide? hehe hopefully i am right cause i dont wanna sound stupid Link to comment Share on other sites More sharing options...
Crash Posted February 20, 2004 Share Posted February 20, 2004 im guessing its HCl?, if so the CaCO3 is being turned into Calcium Chlroide,with carbon dioxide gas and a bit of good ol H2O for good measure. Correct me anybody if im wrong but thats what i get the impresion of for whats happining here Link to comment Share on other sites More sharing options...
neo007 Posted February 20, 2004 Share Posted February 20, 2004 Yep, Crash, what you said is correct. The egg shell is made out of calcium carbonate (CaCO3) and the dilute acid (lets just say hyrdochloric acid, although it doesn't really matter), reacts with the shell to give three products calcium chloride, carbon dioxide and water. This is summarised below CaCO3 + 2HCL------>CaCl2 + CO2 + H2O Link to comment Share on other sites More sharing options...
YT2095 Posted February 20, 2004 Share Posted February 20, 2004 with the exception of Sulphuric acid, and it will react a little at 1`st then slow right down as a not very solluable layer of calcium sulphate forms a semi-protective layer over it Link to comment Share on other sites More sharing options...

Ice_Phoenix87 Posted February 20, 2004 Author Share Posted February 20, 2004 hehe, i am using acetic acid to desolve the calcium carbonate Link to comment Share on other sites More sharing options...
YT2095 Posted February 20, 2004 Share Posted February 20, 2004 another surprise will be in a few days or longer, it will actualy start to "Cook" the egg also Link to comment Share on other sites More sharing options...
