 · 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.

Sedimentary Rocks

Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals.When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.

What Are the Uses of Limestone?

 · Limestone''s usefulness stems from its strength and density. Limestone also is used as roofing granules, a coating that helps shingles resist the heat and weathering. Floor tiles, window sills, facing stone and stair treads are commonly made from limestone blocks. Crushing limestone to the size of sand particles creates a useful material for ...

Lime Production from Limestone

Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it''s use.

Acid Rain

Even those parts of marble and limestone structures that are not themselves eroded can be damaged by this process (Equation 9). When the water dries, it leaves behind the ions that were dissolved in it. When a solution containing calcium and sulfate ions dries, the ions crystallize as CaSO 4 l 2H 2 O, which is gypsum. Gypsum is soluble in water ...
