The acidity is due to the presence of gases like sulfur and nitrogen compounds (SO2, SO3, NO2 ) as well as carbon dioxide. These combine with the water to form acidic solutions. In cases of extremely concentrated pollutants, this can form "acid rain" which is destructive to soil and to human building materials.

What will be the color change if rainwater is dipped into a blue litmus paper?
as rain water is slightly acidic so will turn the blue litmus paper a little red.
Is rainwater acid or alkali or neutral?
It all depends on what is in it. You have heard about acid rain but normal rain has a pH of around 5. It would be slightly acidic according to your question.
Carbon dioxide forms a weak acid called carbonic acid when dissolved in water How can this be a significant factor in the formation of acid rain?
Carbon dioxide in the atmosphere is dissolved in water, making natural rainwater slightly acidic, so when other gases such as sulphur dioxide are dissolved in rainwater, it becomes more acidic than it would be if it didn't contain carbonic acid.
Is seawater acidic or alkaline?
It is very slightly acidic.
What color does litmus paper turn when dipped in urine?
It turns red because rainwater is slightly acidic and litmus turns red in the presence of acids
Is melted snow basic or acidic?
Could be either, although it's essentially rainwater, which is normally acidic.
Suggest why normal rain water is slightly acidic?
Normal rainwater has a pH of 5.6 (slightly acidic). This is because it is exposed to the carbon dioxide in the atmosphere. The carbon dioxide gets dissolved in the rainwater and forms carbonic acid (H{-2}CO{-3}).
Is normal rainwater an acid or a base?
Normal rain water is slightly acidic because contain carbon dioxide.
Is rainwater natrually 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 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.
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 is the pH of natural rainwater?
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
Normal rainwater is slightly acidic because water vapor combines with carbon dioxide in the atmosphere to form?
Carbonic acid yo
Calcium carbonate is insoluble in pure water why does it dissolve in rain water?
Because rainwater, with the different chemicals and elements in it, is very slightly acidic.
Why does rainwater weather away limestone buildings?
Because rainwater is mildly acidic. Acid in the rainwater dissolves the limestone.
What will be the color change if rainwater is dipped into a blue litmus paper?
as rain water is slightly acidic so will turn the blue litmus paper a little red.
Why rainwater is not acidic?
because it does not contain acid
