carbonic acid
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.
If sulphur dioxide and nitrogen dioxide are in the atmosphere and they mix with the water vapour then it falls as acid rain
Rainwater is naturally slightly acidic because carbon dioxide from the air dissolves in it. Minerals in rocks may react with the rainwater, causing the rock to be weathered. Some types of rock are easily weathered by chemicals. For example, limestone and chalk are mostly calcium carbonate. When acidic rainwater falls on limestone or chalk, a chemical reaction happens. New, soluble, substances are formed in the reaction. These dissolve in the water, and then are washed away, weathering the rock. -BBC: The rock cycle
When acid falls on marble surface bubbles of carbon dioxide are released
It falls.
Carbon dioxide is produced.
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.
This will depend entirely on the area in question and atmospheric composition but usually the pH is just under neutral (7) due to dissolved Carbon Dioxide in the rain making it slightly acidic.
Carbon dioxide. Niagara Falls produces electric power from the kinetic energy of water falling through a large vertical drop. This process does not produce carbon dioxide so does not put huge amounts of greenhouse gas into the atmosphere.
Carbon dioxide combines with water to form Carbonic Acid, Similarly Sulfur dioxide form Sulfuric acid and Nitric oxide form Nitric acid. These all falls on earth in the form of acid rain.
I'm pretty sure it's acid rain
Rainwater tanks are used to catch rainwater which falls from the sky when precipitation occurs. This is a great water saving device which can cut the cost of your water bills.
