What Is The Chemical Reaction Between Acid Rain And Marble

Students know how to calculate ph from hydrogen ion concentration.

What is the chemical reaction between acid rain and marble. 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. What effect does acid rain have on marble. Acid rain is composed of sulfuric acid h2so4 or nitric acid hno3 formed as secondary pollutants from so2 other sulfur oxides and nitrogen monoxide no. Acid rain is formed when nitrogen oxides or sulfur oxides in the atmosphere react with suspended water droplets and produce acids.

Stone surface material may be lost all over or only in spots that are more reactive. Students know buffers stabilize ph in acid base reactions. Students know how to use the ph scale to characterize acid and base solutions. How does this happen.

Marble like all calcareous rocks is particularly sensitive to degradation by acid chemicals and to weathering. 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. This black crust is primarily composed of gypsum a mineral that forms from the reaction between calcite water and sulfuric acid. Although these are recognized as highly durable materials buildings and outdoor monuments made of marble and limestone are now being gradually eroded away by acid rain.

However sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled peeled off in some places revealing crumbling stone beneath. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. For example a dramatic increase in the acidity of rain and snow over the past 150 years is dissolving marble and limestone surfaces accelerating the corrosion of metal objects and decreasing the ph of natural waters. So 2 hoh h 2 so 3 the reaction equation for acid rain produced from nitrogen oxides is.

Marble is mainly calcium carbonate. Acid base reactions can have a strong environmental impact. The chemical reaction equation for the production of acid rain resulting from sulfur oxides is. Caco3 s 2hcl aq cacl2 aq h2o l co2 g multiple factors can impact on the rate of the reaction between the acidic factors and the marble particles.

2no 2 hoh hno 2 hno 3. Acid rain contains carbonic acid nitric acid and sulphuric acid co2 no2 and so2. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. The chemical equation that is going to be followed throughout the experiment will be.
