Acid Rain is caused by pollution containing sulfur
dioxide, nitrogen oxide, and ozone ( SOż, NOx, and Oż ) 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 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 ( potential Hydrogen ) scale,
rise exponentialy, thus, 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 ( 5.8 ) to 4.
Acid Rain has been known to reach the acidicy of pH 2, (
battery acid has a pH if 1 ) this is a drastic change, as
normal rain is average pH 5.2.
Acid Rain can dissolve limestone and chalk, and corrodes
outdoor structures. Statues and monuments that are left
unprotected can fall victim to the unpredjudiced
destruction of acid rain.
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 acidicy of
already acidic rocks and soil,
such as granite, or the soil which results from corroded
Acidic chemicals, and alkaline chemicals react to each
other by reducing the alkalinity or acidicy 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
knowledge led to the use of Salting.
Salting ( dropping salt, chalk, or limestone into lakes and
streams ) is a done to reduce the acidicy of the water, and
neutralize the water, counteracting the effects of the acid
rain. This involves literally tonnes of salt, and an
Airplane with a bombay. This is only a temporary solution,
as putting salt into the water will not stop the acid from
coming, it just neutralizes what is already there.
