    What happens when acid reacts with limestone?

    15-06-2008· Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve.

    Calcitic limestone contains 36-38% calcium and can safely be fed free choice (ad lib) mixed with salt. Dolomitic limestone contains at least 5 % magnesium carbonate and should not be used for poultry, but it is as good as calcitic limestone for other animals. Portland and natural cement can be used instead of limestone.
