pH is a measure of the concentration of hydrogen ions (mol dmsup-3/sup) in a solution.
Use the following equation to calculate pH when the concentration of Hsup+/sup is known:
(pH = - \log10{H+} )
This can be rearranged into the following equation, which is used to calculate the concentration of Hsup+/sup when the pH is known:
(H+ = 10-pH )
(pH = - \log10{H+} )
