Not all rain is considered pure water because as rain falls from the atmosphere it collects impurities from particles in the air, such as carbon dioxide, which is a weak acid. Most rainwater, ultimately, has a pH between 5 and 7. Making it slightly acidic.

Yes, rainwater is naturally slightly acidic due to the presence of carbon dioxide in the atmosphere. Carbon dioxide mixes with rainwater to form carbonic acid, which lowers the pH of the rainwater. However, human activities, such as emissions from burning fossil fuels, can increase the acidity of rainwater to harmful levels, leading to acid rain.

Why does rainwater weather away limestone buildings?
Because rainwater is mildly acidic. Acid in the rainwater dissolves the limestone.
Why the normal pH of rainwater is acidic?
Rainwater is normally acidic because the carbon dioxide in the air which mixes with rainwater to form weak acid. That's why its acidic ^_^ Rainwater is also because of the pollutions in the air and it mixes with the water so its not good. meee!
Why does rainwater in polluted areas cause rocks to weather faster than they usually do?
The rainwater is more acidic after passing through polluted air.
Why rainwater has a naturally acidic on limestone buildings?
As rainwater falls to earth, it absorbs pollution (natural and industrial) in the atmosphere which turns the rainwater slightly acidic. Limestone is affected by the acidity, and weathering and erosion is the result. The more pollution, the stronger the acidity, and the more damage is done to buildings and statues made from limestone.
What kind of carbon dissolves in rainwater?
Carbon dioxide (CO2) is the most common form of carbon that dissolves in rainwater. When CO2 from the atmosphere combines with rainwater, it forms carbonic acid (H2CO3), which is responsible for the mildly acidic nature of rain. This dissolved carbon in rainwater can then be utilized by plants for photosynthesis or can react with minerals in soil and water bodies.
Why does rainwater weather away limestone buildings?
Because rainwater is mildly acidic. Acid in the rainwater dissolves the limestone.
Why rainwater is not acidic?
because it does not contain acid
Is rainwater acidic neutral or basic in california?
Rain water is generally acidic
Is rainwater betTer then well water?
That depends where you live. Acidic rainwater is not always better than groundwater.
What kind of weathering is caused by acidic rainwater?
Erosion I think :-)
Does naturally acidic rainwater contain carbonic acid?
Yes it can
Why the normal pH of rainwater is acidic?
Rainwater is normally acidic because the carbon dioxide in the air which mixes with rainwater to form weak acid. That's why its acidic ^_^ Rainwater is also because of the pollutions in the air and it mixes with the water so its not good. meee!
What are the pollutants found in air which make rainwater more acidic?
salt salt makes it more acidic
Is melted snow basic or acidic?
Could be either, although it's essentially rainwater, which is normally acidic.
What makes rain acidic?
Rain is natrually acidic due to the presence of carbon dioxide to produce carbonic acid. CO2 + H2O --> H2CO3 Sulfur dioxide from volcanoes can also contribute to natural acidity 2SO2 + 2H2O + O2 --> 2H2SO4 Rainwater can be made even more acidic due to sulfur dioxide and nitrogen dioxide from burning fossil fuels reacting to form sulfuric acid and nitric acid respectively. 3NO2 + H2O --> 2HNO3 + NO
Why does rainwater in polluted areas cause rocks to weather faster than they usually do?
The rainwater is more acidic after passing through polluted air.
What causes rainwater to be acidic?
Atmospheric sulfur dioxide that dissolves in it on its way down.
