A: Calcium carbonate is a type of hydrogenous sediment that can be buried and hardened into limestone.
Metamorphic limestone. If, over time, a body of limestone has been squeezed and deformed by great heat and pressure deep beneath the Earth's surface, its structure and composition changes to form a recrystallised limestone known as marble, which can contain over 95% calcium carbonate. Marble is a hard crystalline rock that …
In medical industry, limestone is made into high-purity calcium carbonate through a series of technological processes such as crushing, ultra-fine grinding, and purification. A large number of calcium supplements mostly use calcium carbonate as the "calcium source".

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 …
