Powers of Ten and pH
How does this relate to pH? The numbers on the pH scale
run from 0 to 14. Substances with lower pH's have much much more
hydrogen, or H+, than substances with higher pH's. For
example:
 Vinegar,
with a pH of 3, has ten times more H+ than lemon juice, with
a pH of 4.
 Lemon juice,
with a pH of 4, has ten times more H+ than aspirin water, with
a pH of 5.
 Aspirin water,
with a pH of 5, has ten times more H+ than milk, with a pH of
6.
Vinegar has 10 X 10 X 10 or 1,000 times more
H+ than milk. That's a lot! In other words, every notch down
the pH scale has ten times the amount of hydrogen as the notch
above it. See the table below for more details.
