Jan 25, 2018· Chemically limestone is Calcium carbonate (CaCO3). So,When it reacts with HCl it forms Calcium chloride and Hydrogen Carbonate. CaCO3+HCl=CaCl2+H2CO3 is a very unstable compound and it readily breaks into Carbon dioxide and Water. Again, CaCO3+H...
Apr 24, 2017· Limestone is a soft sedimentary rock in which calcium carbonate is present. Limestone is derived from fossil deposits of marine animals and is often a buff or off-white color. It is possible to sand limestone, but only professionals should do so. If you have no experience in working with limestone .
In this interactive, learn about limestone's origins, formation, properties and uses with geologists Professor Cam Nelson and Dr Steve Hood. Given limestone's many uses and applications its ubiquity in the landscape, this 'fizzy rock' deserves closer inspection. To use this interactive, move your mouse or finger over any of the labelled boxes and click to obtain more information.
Pure white marble is the result of metamorphism of a very pure limestone or dolomite protolith that is silicate poor rock. The characteristic swirls and veins of many coloured marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides or chert which were originally present as grains or layers in the limestone.
These gypsum coverings were studied in natural rocks such as limestone and marble [4,5]. The H+ ions of the sulfuric acid dissolve CaCO3 and Ca(OH)2, while the simultaneous reaction of SO42-with Ca2+ causes deterioration due to the deposition of gypsum on the surface of cementitious material [6].
Limestone is a soft, even-grained, sedimentary stone that cannot be polished. Marble is a metamorphic stone that was once limestone; it is somewhat harder, usually has pronounced vein patterns, and can be polished to a mirror sheen. Granite is a very hard igneous stone that can also be polished.
Within a minute, you should see bubbles forming around your limestone rock! The Science behind the Experiment: Vinegar is an acid and as it interacts with the calcium carbonate in the limestone, it releases carbon dioxide -- and when carbon dioxide is released in a liquid, it forms bubbles.
Acid rain is created when industrial and other modern processes release sulfur compounds into the atmosphere. These react with water, creating sulfuric acid, the major active constituent of acid rain. This dissolved acid is carried with rain onto limestone or marble, and .
carbon dioxide: when it mixes with rain& water will create carbonic acid rain which weathers marble and limestone. so carbonic acid weathers marble and limestone. ...
May 24, 2011· Limestone is used as raw material for several products while marble is suitable for use in creating sculptured works of art. 3.Limestone is a sedimentary rock while marble is a metamorphic rock. 4.Heat and pressure causes the formation of marble while they are not necessary for the formation of limestone.
Apr 17, 2013· The following is an identification guide to several standard types of stone used in sculptures, carving, building construction and similar. The types covered are marble, granite, sandstone, limestone, alabaster and soapstone. *** Marble Marble is a high end stone used to make everything from Michelangelo sculptures to mansion steps and walls for mansions.
Limestone and (to a lesser extent) marble are reactive to acid solutions, making acid rain a significant problem to the preservation of artifacts made from this stone. Many limestone statues and building surfaces have suffered severe damage due to acid rain.
Jun 15, 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
The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric ...
The calcite in the limestone changes and fossils and layering in the original limestone disappear as interlocking grains grow. If the limestone is pure, a white marble is formed. Limestones may include layers of clay or sand which may form the attractive flow banding and colours found in decorative marble. Uses of marble: Building Stone
Science fair projects - Effect of acid rain on buildings - view this science fair projects ... The science project was done using marble, limestone, granite and brick. Hypothesis. Between marble, limestone, granite and bricks. limestone suffers the most damage from acid rain. ... How dies acid precipitation affect marble and limestone buildings ...
Apr 25, 2017· More pure quartzite can be used to make ferrosilicon, silicon carbide and silica sand. Marble is also used in buildings, for such things as floor tiles, counter tops, tabletops and lavatories. However, marble is also used for monuments and sculpture, where white marble is most popular.
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, H 2 CO 3, in the water.
Nov 30, 2013· Limestone vs Marble . Both limestone and marble are types of rock made of calcium carbonate residues. Even though their chemical nature is almost similar to each other, there are many differences between limestone and marble in the way they originate and .

How does acid precipitation affect marble and limestone buildings? Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfurous, sulfuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves.

(Sedimentary, Igneous, Metamorphic) ... Bubbles of gas are produce when acid is placed on me. Conglomerate. 1. I am a metamorphic rock. 2. I am a nonfoliated.
Marble is a mineral that is more susceptible to chemical weathering. ... Glass is made from limestone and sand. Limestone is added just before the heating process to form glass to help protect it ...
Nov 04, 2011· The key difference between gypsum and limestone is that the calcium sulfate is the main constituent in gypsum whereas calcium carbonate is the main constituent of limestone.. Limestone and gypsum are minerals that form from calcium salts; limestone contains calcium carbonate while gypsum contains CaSO 4 ·2H 2 O. However, their properties and usages are different from each other.
