Acid rain And its effects

  Acid rain And Its Effects

Acid Rain, Acidity is measured employing a scale called the pH . This scale goes from 0 to 14. 0 is that the most acidic and 14 is that the most alkaline (opposite of acidic). Acid Rain, Something with a pH value of seven , we call neutral, this suggests that it's neither acidic nor alkaline.

Very strong acids will burn if they touch your skin and may even destroy metals. acid precipitation is far , much weaker than this, never acidic enough to burn your skin.

Acid Rain, Rain is usually slightly acidic because it mixes with present oxides within the air. Unpolluted rain would have a pH value of between 5 and 6. When the air becomes more polluted with nitrogen oxides and sulfur dioxide the acidity can increase to a pH value of 4. Some rain has even been recorded as being pH2.

Acid rain are often carried great distances within the atmosphere, not just between countries but also fromcontinent to continent. Acid Rain, The acid also can take the shape 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 significant effect on soil, trees, buildings and water.

Acid Rain, It is thought that acid precipitation can cause trees to grow more slowly or maybe to die but scientists have found that it's not the sole cause. an equivalent amount of acid precipitation seems to possess more effect in some areas than it does in others.

As acid precipitation falls on a forest it trickles through the leaves of the trees and runs down into the soil below. Acid Rain, a number of it finds its way into streams then on into rivers and lakes. Some sorts of soil can help to neutralise the acid - they need what's called a "buffering capacity".

Acid Rain, may be a results of pollution . When any sort of fuel is burnt, many different chemicals are produced. The smoke that comes from a fireplace or the fumes that begin of a car exhaust don't just contain the sooty grey particles that you simply can see - they also contains many invisible gases which will be even more harmfulto our surroundings . Acid Rain, Power stations, factories and cars all burn fuels and thus all of them produce polluting gases. a number of these gases (especially nitrogen oxides and sulphur dioxide) react with the small droplets of water in clouds to make sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it's referred to as "acid rain".
