What happens when acid reacts with limestone? | Questions ...Jun 15, 2008· Answer. 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.
Why Is Limestone Good to Use As Building Material ...Limestone generally forms on the shallow floors of tropical waters when seashells, sand and other sediment are compressed together. Limestone can be called a young marble. Crystals of cement grow around the young marble from grains that are made from animal seashells. A famous architectural marvel created with limestone is the Great Pyramid of Giza.
