What happens when acid reacts with limestone? | Questions | …

 · The concentration of the acid determines how many protons (hydrogen ions) it can donate to react with the marble. You need 2 hydrogen ions per carbonate group. The stronger the acid, the more protons and the more CO 2 you can make: 2H + + CO 3 2--> H 2 O + CO 2

Where to Find Rocks

 · This mineral is very soluble in both water and hydrochloric acid, which readily releases copper that can then be absorbed by the body and, in large enough quantities, could cause copper poisoning. The good news is that one of symptoms of ingesting chalcanthite is vomiting – one of the first things your body does with chalcanthite is try to spit it right back out.
