What happens when acid reacts with limestone?

2008-6-15  Sulphuric acid is a very strong acid but it won't react very well with calcium carbonate because one product of the reaction is calcium sulphate. This is plaster of paris and is insoluble. As a result, it forms a protective layer around the limestone, preventing further access by the acid and effectively stopping the reaction.
