  • What happens when acid reacts with limestone Questions

    Jun 15 2008 · 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.
