10.6 - pH and pOH Scales

pH and pOH are quantitative ways to express solutions of acids and bases. The pH scale is a more convenient way than using exponential notation for expressing concentration of hydrogen ions.

In general, for any hydrogen ion concentration of

1 x 10-n moles/liter = [H+]

the pH is equal to

pH = n

Here is how it works mathematically.

The pH Scale

 

 

In general, for any hydroxide ion concentration of

1 x 10-n moles/liter = [OH-]

the pOH is equal to

pOH = n

When the solution's pH is added to its pOH, the result is always equal to 14.

pH + pOH = 14
