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

[Crash]

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

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

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

well that i didn't know!

hehe, i am using acetic acid to desolve the calcium carbonate

another surprise will be in a few days or longer, it will actualy start to "Cook" the egg also

mmmmmmmm delicious,

 

why are you doing this Ice?

[Ice_Phoenix87]

just to see what would happen. I do that alot
