Two students performed the Acid Rain experiment, their hypothesis, procedure, and data is indicated below. Hypothesis: If we soak marble, limestone, red sandstone, and pea stone in vinegar for two days, then the pea stone will have the smallest change in mass (and therefore be the best building material to resist acid rain).
The purpose of this experiment is to discover the reaction rate in which acid rain weathers marble statues, or in our case, marble chips. The different concentrations of diluted water mixed with hydrochloric acid. The mass of the marble chips in each test tube. To ensure it is a fair test. The
Over time, statues made of marble will suffer ill effects from exposure to acid rain. Objectives The objectives in this investigation are (1) to demonstrate and measure the effect of acid rain on exposed stone surfaces, and (2) to calculate the rate of acid degradation of limestone.
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. In exposed areas of buildings and statues, we see roughened surfaces, removal of
Engineering Connection Acid rain is a complex environmental problem that concerns many environmental and chemical engineers. When engineers examine the acid rain damage to water, wildlife, forests, crops and structures, they consider the impact on human health.
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure.
Acid rain triggers a number of inorganic and biochemical reactions with deleterious environmental effects, making this a growing environmental problem worldwide. Many lakes have become so acidic that fish cannot live in them anymore.
Marble is calcium carbonate and thus behaves in the same way: CaCO3 (s) + 2HCL (aq) CaCL2 (aq) + H2O (l) +CO2 (g) In this experiment, I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. I predict the higher the temperature, the faster the reaction rate. This is due to the kinetic ...
The chemical process of interest here is the reaction between acid solutionan and marble chips. This reaction is of This reaction is of significant interest to preservationists because of the well-documented erosive effect of acid rain on marble statues

Acid Rain Experiments Background Acid precipitation is defined to have a pH lower than 5.6. In New York, the average pH of rainfall is 4.0-4.5 and individual storms as low as 3.0 are not unusual. Freshwater lakes commonly are slightly basic. pH's in the range of 6.5 to 8.2 are optimal for most organisms, and below 5.0 is lethal to many fish species. The susceptibility of lakes to changes in pH ...
Collect the equipment listed above in the materials section from your teacher, and perform the following experiment. 1. Label each of the 12 glass containers with the group name/number. 2. Label 6 of the glass containers "distilled water" and the other 6 glass containers "acid rain." 3. Place a small sample of copper into one of the containers marked "distilled water" and another sample of ...
In your experiment, vinegar will simulate acid rain. You have been provided with the following materials and equipment. It may not be necessary to use all of the equipment that has been provided. You have been provided with the following materials and equipment.
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details.
