The pH of unpolluted rainwater is typically around 5.6, making it slightly acidic due to the presence of carbon dioxide in the atmosphere.
The pH value of unpolluted rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere.
The pH of unpolluted rainwater is typically around 5.6, which is slightly acidic. This acidity is primarily due to the presence of carbon dioxide in the atmosphere, which forms carbonic acid when dissolved in water.
Natural unpolluted rainwater is precipitation that falls directly from the atmosphere without experiencing any contamination or pollution from human activities or environmental sources. It is typically considered safe for consumption and various uses without the need for extensive treatment processes.
The pH of natural rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere that forms carbonic acid when dissolved in rainwater.
Sulfur dioxide and nitrogen oxides are primarily responsible for increasing the acidity of rainwater, forming sulfuric acid and nitric acid when they react with water in the atmosphere. Other acidic substances can also contribute, such as carbon dioxide and certain industrial emissions.
