What else can I help you with?
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.
What is the average pH level of acid rain?
Regular rain water is slightly acidic, with a pH of about 5.6 due to the presence of carbonic acid from the reaction between carbon dioxide and water. Acid rain pH has been recorded as low as 2.0 with an average value of 4.3.
What is the pH difference between acid rain and pure water?
Pure water has a pH of 7.0, while acid rain has a pH or 5.0 or less. The difference in pH would be 2.0 or greater, depending on how acidic the acid rain is.
Carbon dioxide makes rainwater acidic by?
reacting with the water to form carbonic acid. :)
Why does calcium carbonate dissolve in rainwater when it is insoluble in pure water?
Because rain water is not always "pure water", in fact it usually isn't. Rain water always contains carbonic acid (from CO2) and often contains a small amount of sulfuric acid from the various sulfa compounds released by industry, cars, and volcanoes.
Different types of acid rain?
carbonic acid rain and sulfuric acid rain
What acid is present in normal rain?
Carbonic acid.
What is the source of Carbonic acids in swimming pools?
Carbonic Acid, H2CO3 , or acid rain, is derived from rain mixing with the carbon dioxide in the air.
Is acid rain is made from small amounts of acetic and carbonic acids?
Acid rain contain carbonic acid, sulfuric acid, nitric acid.Acid rains are very dangerous for metallic structures and plants.

When rain and CO2 combines what happens?
When rain combines with CO2, it forms a weak acid called carbonic acid. This process is known as carbonation. Over time, carbonic acid can react with and dissolve certain minerals in rocks, contributing to weathering and erosion of the Earth's surface.
Does Carbon dioxide CO2 form Carbonic acid H2CO3 as acid rain as well?
H2CO3 is a naturally occurring form of acid rain.
What is an agent of chemical weathering which combines with water to form a Carbonic acid?
Carbon Dioxide from the atmosphere combines with water to form carbonic acid, it is a form of acid rain.
What is pH of acid rain?
Acid rain has a pH of 5.0 or less. Rain reacts with carbon dioxide in the atmosphere and forms a mildly acidic carbonic acid before it becomes rain.
What two acids are in acid rain?
the two acids are sulfuric acid and nitric acid
What is reason for acid rain?
The rain becomes acidic because Carbon dioxide, Sulphur dioxide and Nitrogen dioxide dissolve in rain drops to form Carbonic acid, Sulphuric acid and Nitric acid.
Is rain water an acid?
Yes. Rain water is mildly acidic as it contains small amounts of carbonic acid and possibly sulfuric and nitric acid.
