Acid rain is rain that has a lower pH level due to water molecules reacting with sulfur dioxide and nitrogen oxides. Because of this, rainwater is much less corrosive than acid rain, with wear only being seen after very long periods of time.

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.


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


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.


Carbon dioxide makes rainwater acidic by?

reacting with the water to form carbonic acid. :)


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.


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.


Is rain acidic or alkaline?

Unpolluted rain should be neutral but many pollutants are acidic (oxides, dioxides and trioxides of Sulphur and Nitrogen in particular). These can become dissolved in rainwater it cause it to become acidic.
