1. All living organisms require specific pH ranges in order for their cells to function properly.
2. pH – potential Hydrogen (H+) in water or whatever liquid is being measured.
3. In more everyday terms, pH is a unit of measure for determining if a liquid is acidic or basic (alkaline).
4. pH is measured on a scale of 0.0 to 14.0.
a. Numbers < 7.0 = acidic
b. Numbers > 7.0 = basic
c. A pH of 7.0 indicates a neutral liquid
a. Liquid with a pH of 6.0 = 10X more acidic than
pure water (pH=7.0).
b. Liquid with a pH of 5.0 =100 X(10x10)
more acidic than pure water.
c. Liquid with a pH of 8.0 is ten times more basic
than pure water.
d. Liquid with a pH of 9.0 is one hundred times more
basic than pure water.
