because it does not contain acid
Rain water is generally 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!
That depends where you live. Acidic rainwater is not always better than groundwater.
Unpolluted rainwater can be slightly acidic due to the presence of carbon dioxide in the atmosphere, which reacts with water to form carbonic acid. This natural acidity of rainwater is typically very mild and not harmful to the environment.
Erosion I think :-)
Yes it can
salt salt makes it more acidic
Could be either, although it's essentially rainwater, which is normally 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.
Rainwater in polluted areas contains acidic compounds that can react with the minerals in rocks, causing them to break down more rapidly through a process known as chemical weathering. This acidic rainwater accelerates the dissolution of mineral grains in the rock, leading to faster weathering rates compared to areas with cleaner rainwater.
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.
Rainwater in industrial areas becomes more acidic due to pollutants such as sulfur dioxide and nitrogen oxides released by factories and power plants. These pollutants combine with water vapor to form sulfuric and nitric acids, lowering the pH of rainwater.
