What else can I help you with?
Is rain water acidic?
Yes, rainwater is slightly acidic due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when it combines with water. The pH of rainwater is typically around 5.6, making it slightly acidic.
Why would unpolluted rainwater be classified as acidic?
Unpolluted rainwater can be slightly acidic due to the presence of carbon dioxide in the atmosphere, which reacts with water to form carbonic acid. This natural acidity of rainwater is typically very mild and not harmful to the environment.
Why is rainwater normally slightly acidic?
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.
Can rainwater dissolve solid bedrock?
Yes, over long periods of time, rainwater can dissolve solid bedrock through a process called chemical weathering. Rainwater is slightly acidic due to carbon dioxide in the atmosphere, which can react with minerals in the bedrock, gradually breaking it down. This process is slow and usually takes thousands to millions of years to significantly change the bedrock.
What will be the color change if rainwater is dipped into a blue litmus paper?
If rainwater is dipped into a blue litmus paper, there will likely be no color change. Blue litmus paper turns red in the presence of an acid, but rainwater is typically slightly acidic due to dissolved carbon dioxide, which is not strong enough to turn blue litmus red.
Is rain water acidic?
Yes, rainwater is slightly acidic due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when it combines with water. The pH of rainwater is typically around 5.6, making it slightly acidic.
Why does rainwater weather away limestone buildings?
Rainwater is slightly acidic due to the presence of carbon dioxide, which can react with the calcium carbonate in limestone to dissolve and weaken the stone over time. This process, known as carbonation, causes erosion and weathering of limestone buildings, leading to their deterioration.
Why would unpolluted rainwater be classified as acidic?
Unpolluted rainwater can be slightly acidic due to the presence of carbon dioxide in the atmosphere, which reacts with water to form carbonic acid. This natural acidity of rainwater is typically very mild and not harmful to the environment.

In cases of extremely concentrated pollutants, this can form "acid rain" which is destructive to soil and to human building materials.
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}).
Which sectence correctly compars the acidty of natural rainwater?
Natural rainwater is typically more acidic than neutral water because it absorbs carbon dioxide from the atmosphere, forming carbonic acid. This makes rainwater slightly acidic with a pH around 5.6.
Is normal rainwater an acid or a base?
Normal rain water is slightly acidic because contain carbon dioxide.
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.
Is rainwater natrually acidic?
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.
How can dolomite be chemically weathered by rain water?
Dolomite can be chemically weathered by rainwater through a process called carbonation. Rainwater, which is slightly acidic due to dissolved carbon dioxide, reacts with dolomite to form carbonic acid. This acid then reacts with the dolomite, dissolving it and releasing calcium and magnesium ions into the rainwater.
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!
