sulfur dioxide
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.
Acid rain is slightly more acidic (has a lower pH) than normal rain.As an explanation the pHs of common materials (acids and basess) including Acid rain are:Lye 14.0Ammonia water 11.6Eggs 8.0Blood 7.3Distilled water 7.0Saliva 6.0Normal rain 5.7Acid rain 5.2Tomato Juice 4.2Apple Juice 3.0Coke products 2.5 to 4.2Vinegar 2.4
Carbon dioxide (CO2) mixes with water to make a weak carbonic acid
Sulfuric acid
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.
When rainwater mixes with pollutants, it can form acidic rain or polluted runoff. This can harm aquatic ecosystems, contaminate drinking water sources, and damage buildings and infrastructure.
Carbonic acid is a natural acid that can dissolve calcite. It forms when carbon dioxide in the atmosphere dissolves in rainwater or groundwater, creating a weak acid that can slowly dissolve minerals like calcite.
Natural rainwater is typically more acidic than neutral water because it absorbs carbon dioxide from the atmosphere, forming carbonic acid. This makes rainwater slightly acidic with a pH around 5.6.
