pH and pOH difference

Postby Raymond_Guan_1H » Tue Nov 22, 2016 5:28 pm

What exactly is the difference between pH and pOH? Is one only for hydroxide and the other hydronium? What is the scale for pOH?

Hello,
So pH is the measure of hydrogen ion concentration, [H+], while pOH is a measure of the hydroxide ion concentration, [OH-]. The scales for both are 1-14. However in most cases, the question will ask for pH. So remember that pH+pOH=14. So pH=14-pOH.
