Carbonic acid, a very weak acid and in minute dilutions. It arises as a result of carbon dioxide and water reacting in the higher regions of the atmosphere. Sulphuric acid and nitric acid are also commonly found in rainwater in areas where there is atmospheric pollution. Please see the related links.
Normal rain water is slightly acidic because contain carbon dioxide.
It's because there is already natural CO2 in the rain water (from the atmosphere), and CO2 is an acidic gas. In today's world, there is no such thing as unpolluted water. We have successfully polluted the atmosphere and our earth. Our water is full of hydrocarbons, pharmaceuticals, and a plethora of other toxins/pollutants.
sulphuric acid is a stronger acid than carbonic acid. lower pH defines strength of acid.
No
In many cases, in a large part of the world, rain is neutral pH, but in industrial areas, or other polluted areas, rain can be a little bit acid. The interesting thing about acid rain is that it apparently blocks a little of the warming from the sun.
because it does not contain acid
Sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) are three gases that can dissolve in rainwater to form sulfuric acid, nitric acid, and carbonic acid, respectively, resulting in acid rain and lowering the pH of rainwater.
Rain is typically slightly acidic, with a pH around 5.6 due to the presence of carbon dioxide in the atmosphere which forms carbonic acid in the rainwater. This acidity can vary based on location and pollution levels.
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.
