Is acid rain a gas?
Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Is acid rain acidic?
Normal rain is slightly acidic, with a pH of 5.6, while acid rain generally has a pH between 4.2 and 4.4.
Is acid deposition the same as acid rain?
Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain is a type of acid deposition, which can appear in many forms. Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal.
How is acid rain different from regular rain?
Difference Between Acid Rain and Acid Precipitation. Water is a universal solvent. When raining, the rain water tends to dissolve substances, which are dispersed in the atmosphere. Due to human activities today the earth atmosphere has been highly polluted. When there are sulfur dioxide gas and nitrogen oxide gases in the atmosphere,…
How does acid rain affect the Earth’s atmosphere?
Due to human activities today the earth atmosphere has been highly polluted. When there are sulfur dioxide gas and nitrogen oxide gases in the atmosphere, they are easily dissolved in rain water and come down as sulfuric acid and nitric acid. Then the pH of the rain water becomes less than 7, and we say that it is an acidic.
Which is a part of the acid precipitation?
• Acid rain is a part of acid precipitation. Acid rain contains acidic substances, which are dispersed in the atmosphere. Other than rain, acid precipitation involves sleet, snow, fog, and cloud vapor.
What is the pH of carbonic acid in rain?
Carbonic acid is the same as that found in soda pop. The pH of “normal” rain has traditionally been given a value of 5.6. However scientists now believe that the pH of rain may vary from 5.6 to a low of 4.5 with the average value of 5.0. Acid rain or acid snow is a direct result of the method that the atmosphere cleans itself.
