chemical limestone Most limestone forms due to biochemical processes, but the limestone called travertine forms in two different ways due to chemical reactions between charged particles called ions. Wherever water saturated in calcium and carbonate ions evaporates or carbon dioxide escapes from the carbonate ion, layers of calcium carbonate will build up forming terraces and other odd shapes.

Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO 3. The calcium carbonate is originally produced by living organisms. Later, some of it goes into solution in sea water. Limestone rocks include mainly organic remains and precipitated carbonate.

Apr 12, 2017· The term limestone encompasses several forms of sedimentary rock composed primarily of calcium carbonate. Limestone may form from chemical processes instigated by large populations of algae, or may form as the shells from aquatic creatures and singlecelled organisms form a dense layer.

Quicklime is produced by heating naturallyoccurring limestone rock, which contains calcium carbonate. Being highly alkaline in nature, quicklime tends to react with the acidic carbon dioxide present in the atmosphere to again form calcium carbonate, or limestone, from .

Travertine is a banded, compact variety of limestone formed along streams, particularly where there are waterfalls and around hot or cold springs. Calcium carbonate is deposited where evaporation of the water leaves a solution that is supersaturated with chemical constituents of calcite.

Concentric layers are formed and these give the rock its characteristic "egg stone" appearance, as the surface of the rock looks like fish roe (fish eggs). Hence the term oolitic limestone. Oolite (egg stone) is sedimentary rock and although most ooids are formed from the collection of calcium carbonate, this is not always the case as these structures can be composed of phosphate, dolomite or even chert.

Limestone is one familiar form of calcium carbonate. Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate. Because surface waters are in equilibrium with atmospheric carbon dioxide there is a constant concentration of carbonic acid, ...
