What role does calcium carbonate act to prevent acid rain?

Answer 1

CaCo3 is a base, so it neutralizes acids. Thus, CaCo3 can neutralize acids in acid rain. For example, CaCo3 will neutralize HCl by the following equation:

2HCl(aq) +CaCO3(aq) reacts to form CaCl2(aq) + H2O(l) + CO2(g)

This gets rid of the acids and makes the acid rain safe for organisms.

Answer 2

Calcium carbonate chemically reacts with acids (the main acid in acid rain is sulphuric acid formed from sulphur dioxide emissions) to form a salt (e.g. calcium sulphate) + water + carbon dioxide gas. So what you see is 'fizzing' as the gas is evolved, and eventually the rock will disappear or dissolve.

This is because the salt produced is water soluble and is therefore washed away with the water (erosion).

In this way acid rain can easily destroy the details on relief work (e.g, the faces on a statue) of calcium carbonate (marble and limestone) structures.

This process called chemical weathering.

Answer 3

Calcium carbonate, which has the formula CaCO3, is produced as a form of shell or skeleton by many organisms, and is made using carbon dioxide (CO2) as a starting material for the procuction of the carbonate ion. It is relatively insoluble although its solubility increases as water becomes more acidic. It therefore takes carbon dioxide out of the air, and carbon dioxide is of great concern as a greenhouse gas and cause of global warming.

Answer 4

Calcium carbonate can help prevent acid rain by neutralizing acidic compounds such as sulfur dioxide and nitrogen oxides in the atmosphere. When these acidic compounds react with calcium carbonate, they form less harmful substances like water and carbon dioxide. This helps to reduce the acidity of rainwater and lessen its impact on the environment.

Answer 5

Yes. The high concentrations of acidic compounds react with the material, releasing the carbon dioxide in the calcium carbonate.

Answer 6

How much I know that is, Calcium carbonate reacts with the sulphuric acid in the acid rain to form salt, which is not harmful (I think).

Answer 7

dissolved calcium carbonate?
