Sulfuric acid
When rainwater mixes with pollutants, it can create acid rain. Acid rain forms when pollutants such as sulfur dioxide and nitrogen oxides react with water in the atmosphere, resulting in a mixture of sulfuric acid and nitric acid. This acidic precipitation can have negative impacts on the environment, including harming vegetation, damaging buildings, and affecting water quality.
The most common natural acid on Earth's surface is carbonic acid, which forms when carbon dioxide dissolves in water. It is found in rainwater, rivers, lakes, and oceans.
its all to do with gravitational pull, basically rainwater holds carbon dioxide as it is fresh from the atmosphere then when it reaches earth there is more added to it because us humans and animals take in oxygen and breathe out carbon dioxide.
I think it is Nitrogen Oxide. The nitrous oxide condenses with the rain to give the nitric acid, sulfur dioxide condenses with the rain to give sulfuric acid, carbon dioxide combines with the rain to give carbonic acid . These three acids constitute the acid rain.
Carbon dissolves into carbonic acid when it interacts with rainwater. This occurs as carbon dioxide from the atmosphere mixes with water, forming carbonic acid, a weak acid. This process contributes to the natural acidity of rainwater, which can influence soil and water chemistry.
Natural rainwater primarily consists of water vapor that condenses in the atmosphere. It can mix with various atmospheric gases, notably carbon dioxide, which forms carbonic acid, and other pollutants like sulfur dioxide and nitrogen oxides, leading to the formation of acid rain. Additionally, dust and particulate matter can also mix with rainwater, affecting its purity and chemical composition.
Carbon dioxide (CO2) mixes with water to make a weak carbonic acid
Sulfuric acid
Acid rain is primarily formed when sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) mix with natural rainwater. These pollutants are released into the atmosphere through industrial processes, vehicle emissions, and burning fossil fuels. When they combine with water vapor, they create sulfuric and nitric acids, resulting in rain that has a lower pH and can be harmful to the environment.
Sulfur dioxide and nitrogen oxides from human activities, such as burning fossil fuels, react in the atmosphere to form sulfuric acid and nitric acid. These acids are the primary contributors to the increased acidity of acid rain compared to natural rainwater.
Natural rainwater has a pH of around 5.6. I believe rain is considered to be "acid rain" when it has a pH of 5.0 or below.
acid rain
The presence of sulfur dioxide (SO2) and nitrogen oxides (NOx) in the atmosphere can react with water vapor and form sulfuric acid (H2SO4) and nitric acid (HNO3), making the rain more acidic than natural rainwater. These pollutants are primarily released by human activities such as burning fossil fuels and industrial processes.

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!
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
