Calcium carbonate works as a stomach acid remedy and may be applied to resolve digestive failure. Calcium lactate may aid the body during periods of calcium deficiency, and calcium chloride is a diuretic. Hard water may assist in strengthening bones and teeth because of its high calcium concentration. It may also decrease the risk of heart ...
Hydrochloric Acid and Calcium Carbonate Essay Sample. For our coursework investigation we tested how concentration affected the rate of reaction between calcium carbonate and hydrochloric acid. We experimented with the reaction: Calcium Carbonate + Hydrochloric Acid Calcium .
Get an answer for 'What effect does acid rain have on limestone and sandstone?' and find homework help for other Science questions at eNotes. eNotes ... that is composed of calcium carbonate ...
The gaseous oxides (CO 2, NO 2 and SO 2) present in the air as chemical pollutants mix with water in air to form acids such as carbonic acid, nitric acid and sulphuric acid comes down as acid rain and cause corrosion of marble statues and monuments. Calcium carbonate present in marble is transformed into other compounds by reaction with acids as follows:
Figure Acid Rain Damage to a Statue of George Washington. Both marble and limestone consist of CaCO 3, which reacts with acid rain in an acid–base reaction to produce CaSO 4. Because CaSO 4 is somewhat soluble in water, significant damage to the structure can result.
calcium carbonate → calcium oxide + carbon dioxide. ... Calcium hydroxide (also known as slaked lime) is used to neutralise. excess acidity, for example, in lakes and soils affected by acid rain.
Acid rain can damage buildings, historic monuments, and statues, especially those made of rocks, such as limestone and marble, that contain large amounts of calcium carbonate. Acids in the rain react with the calcium compounds in the stones to create gypsum, which then flakes off.
Mar 21, 2010· This is because limestone and marble both have high levels of calcium carbonate. Calcium carbonate is a white, crystalline, waterinsoluble, tasteless powder. Rocks containing calcium carbonate dissolve slowly in acidified rainwater. So when they were left in the model acid rain they slowly dissolved more due to the high levels of calcium ...
Ancient statues made of marble (a form of calcium carbonate) are damaged by acid rain because the reaction between the sulfuric acid in the rain and calcium carbonate produces soluble calcium sulfate, which washes away: CaCO_3(s)+H_2SO_4(aq) rightarrow CaSO_4(aq) + CO_2(g)+H_2O(I). Suppose an engineer decides to study the rate of this reaction.
Apr 15, 2008· The acids lower seawater's pH and strip it of carbonate ions. (Ultimately, so does ammonia, a base, which is converted to nitrates and nitric acid.) That hampers the ability of marine organisms—such as sea urchins, shellfish, corals, and certain types of plankton—to harness calcium carbonate to make hard outer shells or "exoskeletons."
Acid rain is one factor that can increase the rate of erosion, with effects that can be seen in just a few decades. Limestone and marble are composed calcium carbonate, the same material as chalk, and are commonly used for constructing buildings and statues. Rain that is too acidic will "eat away" at these structures very quickly, the same way the vinegar ate away at the chalk. Why does it matter?
The gaseous oxides (CO 2, NO 2 and SO 2) present in the air as chemical pollutants mix with water in air to form acids such as carbonic acid, nitric acid and sulphuric acid comes down as acid rain and cause corrosion of marble statues and carbonate present in marble is transformed into other compounds by reaction with acids as follows:

Acid rain problems have occurred all over this planet, but the problem that is most concerning to me isthe damage acid rain causes to works of art, like statues and buildings. Works of art have been affected by acid rain in many different ways including enviormentally and economicaly/socially.
Taj Mahal, one of the 7 wonders of the world, is largely affected by acid rain. The city of Agra has many industries which emit the oxides of sulphur and nitrogen in the atmosphere. People continue to use lowquality coal and firewood as a domestic fuel, adding to this problem. Acid rain has the following reaction with the marble (calcium ...
Acid rain leaches calcium from the needles of red spruce, making them more susceptible to cold. It also leaches calcium and magnesium from the soil, which can stress sugar maples. In addition, acid rain allows aluminum to accumulate in the soil. When trees take up aluminum, their roots can become brittle.
Acid rain, caused by pollutants being dumped into the atmosphere by humans every day, is destroying the cultural heritage of Mexico's Maya civilization, biologist Pablo Sanchez told EFE.
Sep 16, 2007· Acid rain damages the crops and makes the soil less rain contaminates the water bodies and harms the aquatic damages buildings and statues, specially made of acid rain reacts with marble (Calcium Carbonate) and destroys it.
Jan 28, 2013· Pure water has a pH of (neutral); however, natural, unpolluted rainwater actually has a pH of about (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H +) concentration.]The acidity of rainwater comes from the natural presence of three substances (CO 2, NO, and SO 2) found in the troposphere (the lowest layer of the atmosphere).
Jun 28, 2010· "Acid rain has also been blamed for eating away parts of sandstone buildings and statues by dissolving the calcium carbonate matrix that .
