Acid rain is rain that has been contaminated with pollutants like sulfur dioxide and nitrogen oxides, which makes it even more acidic than natural rainwater. These pollutants are released into the atmosphere through human activities like burning fossil fuels, causing rainwater to become more acidic when it combines with them in the atmosphere.
Normal rain is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid, giving the resulting mixture a pH of approximately 5.6 at typical atmospheric concentrations of CO2. As of 2000, the most acidic rain falling in the U.S. has a pH of about 4.3.
when the harmful fumes from the cars and factories mix with the air ..the rain that falls becomes acidic due to the mixture of carbon dioxide and water..

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.
What is the pH of natural rainwater?
The pH of natural rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when dissolved in rainwater.
Why rain is naturally acidic?
Rain is naturally acidic due to the presence of carbon dioxide in the atmosphere. When carbon dioxide combines with water vapor, it forms carbonic acid, which lowers the pH of the rainwater. Additionally, other pollutants in the atmosphere can also contribute to acid rain formation.
What is the pH of unpolluted rainwater?
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
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 is rain water naturally acidic?
Rainwater is slightly acidic because the CO2 in the atmosphere is soluble in water (the water in the air). When in solution CO2 forms a weak acid (Carbonic acid) which makes pure rainwater a weak acid.
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.
Why is rain not naturally acidic?
Rain is naturally slightly acidic, with a pH of around 5.6, due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when it reacts with water vapor. However, this level of acidity is not harmful and is considered normal for rainwater. Factors such as pollution and industrial activities can increase the acidity of rain, leading to acid rain.
Is acid rain man made?
Acid rain is man made and there is more types of acid. Normal rainwater is actually slighty acidic with a pH of just over 6. This is due to the rain dissolving Carbon Dioxide as it falls through the sky. When a volcano errupts it releases gases such as Sulpher Dioxide into the air which makes the rainwater more acidic with a pH of about 4. Air pollution caused by man also contibutes to the acid rain.
Which substance in acid rain makes it more acidic than natural rainwater?
Sulfuric acid
Why is acid rain colourless?
Acid rain is colorless because it consists of ordinary rainwater that has become acidic due to the presence of pollutants like sulfur dioxide and nitrogen oxides. These pollutants dissolve in the rainwater, making it more acidic, but they do not necessarily change the color of the rain itself.
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.
What is the difference between normal rain and acid rain since normal rain is acidic anyway?
Normal rain is slightly acidic but it occurs naturally, as oppose to acid rain caused by air pollution
Carbon dioxide makes rainwater acidic by?
Carbon dioxide reacts with water in the atmosphere to form carbonic acid, which lowers the pH of rainwater, making it acidic. This process is known as acid rain formation.
How does acid rain make the lake Waters acidic?
Acid rain forms when sulfur dioxide and nitrogen oxides from burning fossil fuels mix with rainwater. When this acidic rainwater falls into lakes, it lowers the pH of the water, making it more acidic. This can harm aquatic life in the lake by disrupting their delicate pH balance.
Is rain acidic or alkaline?
Rain is naturally slightly acidic, with an average pH of around 5.6 due to the presence of carbon dioxide in the atmosphere. When carbon dioxide combines with water, it forms carbonic acid, which lowers the pH of rain.
What happens to rainwater to make it more acidic than usual?
When rainwater becomes more acidic than usual, it is usually due to the presence of pollutants such as sulfur dioxide and nitrogen oxides in the atmosphere. These pollutants combine with water vapor to form sulfuric acid and nitric acid, making the rainwater more acidic. This phenomenon is known as acid rain.
