Acid rain consists of any form of precipitation (rain, snow, fog) which has an unnaturally low (acidic) pH level. The acid consists primarily of sulfuric and nitric. Jump to Wet deposition - "Acid rain" is a popular term referring to the deposition of a mixture from wet (rain, snow, sleet, fog, cloudwater, and dew) and dry (acidifying particles and gases) acidic components. Distilled water, once carbon dioxide is removed, has a neutral pH of 7.‎Acid Rain Program · ‎Acid rain (disambiguation) · ‎Nitrogen oxide · ‎Black Triangle. The common term to describe this process is acid deposition. The term acid precipitation is used to specifically describe wet forms of acid pollution that can be.

Acid Rain: Causes, Effects and Solutions

Acidic and basic are two ways that we describe chemical acid rain deposition. Acidity is measured using a pH scale. The illustration above also describes the pH of some common substances.

Acid deposition acid rain deposition not a recent phenomenon. In the 17th century, scientists noted the ill effects that industry and acidic pollution was having on vegetation and people.

Acid rain, acid deposition

However, the term acid rain was first used two centuries later when Angus Smith published a book acid rain deposition 'Acid Rain' in In the s, the problems associated with acid deposition became an international problem when fishermen noticed declines in fish numbers and diversity in many lakes throughout Acid rain deposition America and Europe.

Acid Deposition Formation Acid deposition can form as a result of two processes. In some cases, hydrochloric acid can be expelled directly into the atmosphere.

More commonly it is due to secondary pollutants that form from the oxidation of nitrogen oxides NOx or sulfur dioxide SO2 gases that are released into the atmosphere see Figure 8h Reactions at the Earth's surface or within the acid rain deposition can convert these pollutants into nitric acid or sulfuric acid.

The process of altering these gases into their acid counterparts can take several days, and during this time these pollutants can be transported hundreds of kilometers from their original source. Acid precipitation formation can also take place at the Earth's surface when nitrogen oxides and sulfur dioxide settle on the landscape and interact with dew or frost.

Acid Rain Students Site: What is acid rain?

The main sources of acid rain deposition include: The smelting of metal sulfide ores to obtain the pure metals. Metals such as zinc, nickel, and copper are all commonly obtained in this manner. Volcanic eruptions - although this is not a widespread problem, a volcanic eruption can add a lot of sulfur to the atmosphere in a regional area.

After being released into the atmosphere, sulfur dioxide can either acid rain deposition deposited on the Earth's surface in the form of dry deposition or it can undergo the following reactions to produce acids that are incorporated into the products of wet deposition Figure 8h Several processes can result in the formation of acid deposition.

Acid Rain: Causes, Effects and Solutions

Nitrogen oxides NOx and sulfur dioxide SO2 released into the atmosphere from a variety of sources call fall to the ground simply acid rain deposition dry deposition. This dry deposition can then be converted into acids when these deposited chemicals meet water.

For example, healthy lakes have a pH of 6. As acid rain raises the level of acidity, fish tend to die off.

Most fish species can't survive a water pH of below 5. When the pH becomes a 4, the lake is considered dead, according to National Acid rain deposition Deposition Program. It can additionally deteriorate limestone and marble buildings and monuments, like gravestones.

Solutions There are several solutions to stopping manmade acid rain. Regulating the emissions coming from vehicles and buildings is an important step, according to the EPA.

What is Acid Rain?

Winds can blow SO2 and NOX over long distances and across borders making acid rain a problem for everyone and not just those who live close to these sources. Forms of Acid Deposition Wet Deposition Wet deposition is what we most commonly think of as acid acid rain deposition.

The sulfuric and nitric acids formed in the atmosphere fall to the ground mixed with rain, snow, fog, or hail. The acidic particles acid rain deposition gases may deposit to surfaces water bodies, vegetation, buildings quickly or may react during atmospheric transport to form larger particles that can be harmful to human health.
