What happens when acid reacts with limestone? Questions ...

Jun 14, 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. Or, if there is more acid, two hydrogen ions will

Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

Chalky soils / RHS Gardening

Alkaline soils are widely distributed in Britain, and many of these will be derived from chalk or limestone and are commonly referred to as chalky. Although they include Britain's most productive agricultural soils they can be a challenge to garden. Chalky soils are often shallow, stony and free-draining, and added organic matter can decompose rapidly, making them difficult to keep fertile.
