pH = -log[H+]
every number on the scale means a 10x reduction or increase in pH
1......2......3......4......5......6
A pH of 1 is 10 times more concentrated than 2, 100x 3, 1000x 4, 10000x 5, ...
*most fluids are 6-8 on the scale*
Ionization
People usually interpret ionization as
| HOH |
|
H+ + OH- |
however, instead of seeing just dissociation there is re-association in the form of a hydronium ion
| HOH |
|
H3O+ |
