Why Does Acid Rain Erode Marble

Marble is ca2co3 which can easily react with acids of any kind to give co2.

Why does acid rain erode marble.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Marble like all calcareous rocks is particularly sensitive to degradation by acid chemicals and to weathering. Never use marble as a working plate in the kitchen. Acid rain contains carbonic nitric and sulfuric acid that are produced by oxidation and dissolution in water of gaseous oxides co 2 no 2 and so 2 present in the air as chemical pollutants.

Destruction of ecosystems like lakes and rivers can occur when they become too acidic which can result in fish and other water dwelling creatures not surviving and no longer being a food source for. Write the formula equation for the reaction between sulfuric acid and calcium carbonate. Atirahmalik4997 05 15 2018 chemistry high school 5 pts. Acid rains are one of the main degradation agents for marble artifacts.

This is because the sulphuric acid in the rain chemically reacts with the calcium compounds in. This acid is weak but can give rain water a slightly acidic ph of around 5 6. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Why does acid rain dissolve statues made of marble caco3.

When this rain water falls it reacts with the claim carbonate present in limestone in the following reaction. This increases the cost of maintaining buildings. Stone surface material may be lost all over or only in spots that are more reactive. Marble ad limstone are bases and they are chemically reacting with the acidic properties of the rain.

Acid rain erosion of limestone and marble can result in a loss of artwork outdoor statues monuments plaques etc that cannot be recovered. When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves.
