Acid Rain What is Acid Rain? Acid rain is a result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. Power stations, factories and cars all burn fuels and therefore they all produce polluting gases.

Some of these gases especially nitrogen oxides and sulphur dioxide react with the tiny droplets of water in clouds to form sulphuric and nitric acids.

The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain". How acidic is acid rain? Acidity is measured using a scale called the pH scale.

This scale goes from 0 to Something with a pH value of 7, we call neutral, this means that it is neither acidic nor alkaline.

Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air.

Unpolluted rain would have a pH value of between 5 and 6. When the air becomes more polluted with nitrogen oxides and sulphur dioxide the acidity can increase to a pH value of 4. Some rain has even been recorded as being pH2. Vinegar has a pH value of 2. The Effects of Acid Rain Acid rain can be carried great distances in the atmosphere, not just between countries but also from continent to continent.

The acid can also take the form of snow, mists and dry dusts. The rain sometimes falls many miles from the source of pollution but wherever it falls it can have a serious effect on soil, trees, buildings and water. Forests all over the world are dying, fish are dying.

In Scandinavia there are dead lakes, which are crystal clear and contain no living creatures or plant life. This leads to fish-eating birds and animals being affected also.

Is acid rain responsible for all this? Scientists have been doing a lot of research into how acid rain affects the environment. Forests It is thought that acid rain can cause trees to grow more slowly or even to die but scientists have found that it is not the only cause.

The same amount of acid rain seems to have more effect in some areas than it does in others. As acid rain falls on a forest it trickles through the leaves of the trees and runs down into the soil below.

Some of it finds its way into streams and then on into rivers and lakes. Some types of soil can help to neutralise the acid - they have what is called a "buffering capacity".

Other soils are already slightly acidic and these are particularly susceptible to the effects of acid rain.

Acid rain can effect trees in several different ways, it may: A combination of these effects weakens the trees which means that they can be more easily attacked by diseases and insects or injured by bad weather. It is not just trees that are affected by acid rain, other plants may also suffer.

Lakes and Rivers It is in aquatic habitats that the effects of acid rain are most obvious.The first step you can take to help control acid rain is to understand the problem and its solutions. Now that you have learned about this environmental issue, you can tell others about it. By telling your classmates, parents, and teachers about what you learned on this site, you can help educate them about the problem of acid rain.

Acid rain is a serious environmental problem occurring all over the world, particularly in large swaths of the United States and Canada. As the name suggests, it . To solve the acid rain problem, people need to understand how acid rain causes damage to the environment.

They also need to understand what changes could be made to the air pollution sources that cause the problem.

Vinegar has a pH value of and lemon juice has a value of pH Even the strongest recorded acid rain is only about as acidic as lemon juice or vinegar and we know that these don't harm us - so why do we worry about acid rain?

The Effects of Acid Rain. Acid rain can be carried great distances in the atmosphere, not just between countries but also from continent to continent. Acid rain describes any form of precipitation with high levels of nitric and sulfuric acids. It can also occur in the form of snow, fog, and tiny bits of dry material that settle to Earth.

Acid rain can be prevented by saving energy, using less transportation, and switching to alternative energy sources.

Reducing fossil fuel consumption stops acid rain before it begins. Lowering energy consumption on a daily basis is the best way to prevent the formation of acid rain.
