The PH test measures the hydrogen ion
concentration in different water samples. All water samples that are measured
for ph are measured on a scales from 0 –14 meaning that anything 0-7 is an acid
and 7 is neutral and anything from 7-14 is basic. All water samples contain
hydrogen (H+) ions and Hydroxide (OH-) ions and the more hydroxide present the
more basic the water is, the more Hydrogen present the more acidic the water
is, and if the water sample has an equal amount of both then the water is
neutral which would be a PH of 7.
A-biotic
- Many non-living things can have an effecct on the amount of PH in a water
sample such as acid, which would greatly increase the acidity of a water mass
causing the death of native organisms and promoting the growth of new organisms
more evolved to withstand the low PH levels. Another non-living influence in PH
levels can be rocks and minerals such as limestone, which is used in many cases
to neutralize the amount of PH in a water sample.
Biotic
- many living things can have an effect onn the amount of PH in a water sample
through people by automobiles and coal fired power plants which increase the
amount of nitrogen oxides and sulfur dioxides which would convert to nitric
acid and sulfuric acid when hitting the atmosphere.
