1. Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone that is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren't absorbed into the clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition.
When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entire body to be raised. Measurments on the pH scale, rise greatly; a lake with a pH of 4 is ten times as acidic as a lake with a pH of 5, and a lake with a pH of 3 is 100 times as acidic, After many rain falls of Acid rain, the pH of a normal lake would go from 5.8 to 4.
Acid Rain has been known to reach the acidity of pH 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. (Alm, 1997)
2. Acid Rain can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected .
Acid Rain reacts to different types of soil and rocks in two ways:
1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity.
2) Acid rain will increase the acidity of already acidic rocks and soil such as granite, or the soil which results comes from corroded granite.
Acidic chemicals, and alkaline chemicals react to each other by reducing the alkalinity or acidity of each other. Which ever has the strongest pH level, usually will neutralize or reduce the pH of the other, but after the reaction is complete both substances have undoubtably changed. Their pH moved closer to neutral ( pH 7 ). This led to the use of Salting.
Salting ( dropping salt, chalk, or limestone into lakes and streams ) is a done to reduce the acidity of the water, and neutralize it reverse the effects of the acid rain. This involves tones of salt and an Airplane with a bombay. This i...
