What is the formula for acid rain?

“Clean” or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid according to the following reaction: H2O (l) + CO2 (g) ⇌ H2CO3 (aq)

How is acid rain formed * 1 Point your answer?

Acid rain is caused by a chemical reaction that begins when compounds such as sulphur dioxide and oxides of nitrogen are released into the air. These substances can rise very high up into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants called acid rain.

What is acid rains pH?

The pH scale measures how acidic an object is. Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.

What is most affected by acid rain?

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

What are the chemical reaction equations for acid rain?

The worded equation for acid rain is as follows: sulfur dioxide + water -> sulfurous acid. sulfur trioxide + water -> sulfuric acid. nitrogen dioxide + water -> nitric acid + nitrous acid.

What is the process of acid rain?

Acid rain occurs when pollution in the atmosphere (sulfur dioxide and nitrogen oxide) is chemically changed and absorbed by water droplets in clouds. When there is precipitation, the droplets fall to earth as rain, snow, or sleet.

What forms acid rain?

The compounds that cause the formation of acid rain are sulfur dioxide and nitrogen oxide. These substances react with oxygen and water in the atmosphere to form acid rain…. The burning of fossil fuels can cause smog and acid rain. Acid rain is precipitation that is unusually acidic.

How is acid rain form?

Acid rain forms when water molecules in the atmosphere react with sulfur dioxide or nitrogen oxides to form an acidic compound.
