pH is a shorthand numerical value that represents the concentration of hydrogen ions in solution.

The scale 0-14 represents the usual range of possible concentrations of protons (

H

+

) in an aqueous system.

We can consider  

H

+

to mean the same as  

H

3

O

+

(a water molecule carries

the  

H

+

).

pH

is the negative log of hydrogen ion concentration, meaning that:

pH

=

log

[

H

3

O

+

]

=

log

[

H

+

]

and therefore:

pH

=

This is counter-intuitive without the background information (i.e. the negative log) but, as you increase pH, you decrease the concentration of  

H

+

.

As you decrease the pH, you increase the concentration of  

H

+

.
