does the acid get into the atmosphere?
fossil fuels like coal, oil, and natural gas, are burned, sulfur
dioxides and nitrogen oxides are released into the air. Any
type of transportation that burns gasoline emits these fumes
into the air. Gasoline is made from one of the major fossil
also burn fossil fuels. LIPA our electric company here on Long
Island burns coal, another fossil fuel, to produce the electricity
in your home. When sulfur dioxides and nitrogen oxides are released
into the atmosphere they form acids.
do these acids make acid rain?
acids mix with the moisture in the air and fall back down to
earth as acid precipitation. Otherwise know as "Acid Rain"
acid rain harmful?
rain damages forests by changing the pH value of the soil. It
does the same thing when it falls into the lakes and streams
on earth. For example, let's say the water in your fish tank
evaporates. As it evaporates instead of adding more fresh water
pH(7) you add a weak acid like one of the ones we tested in school,
orange juice or vinegar. Imagine how your fish would feel swimming
in water that was very acidic. This is generally how acid precipitation
kills aquatic life in the fresh water here on Earth. Acid rain
can even damage statues, cars and buildings.
can you figure out how acidic the rain is?
you look to the left of my web page you will see the pH scale.
We used this scale to test many household items. Substances
pH value of 1- 6 are considered acids. While substance with a
pH value of 8 - 14 are basic or alkaline. The general rule is
the further away the substance pH value is from 7 (neutral) the
stronger is t is. For example. An acid with a pH of 3 is stronger
than a an acid with a pH of 4. Because 3 is further away from
7. Same works for alkalines. An alkaline with a pH value of 14
is stronger than a substance whose ph value is 8, because 14
is further away from 7.
