pH and pOH
What is the difference between pH and pOH, what do they do, and how do you calculate them?

Re: pH and pOH
The pH scale measures the H+ concentration while the pOH scale measures the OH- concentration. Depending on which value you are given, one way to calculate the pH or the pOH of a solution is pH + pOH = 14.

Re: pH and pOH
pH represents the concentration of H+ while pOH is a measure of concentration of OH-. You would calculate the value by taking the -log of concentration of the substance.

Re: pH and pOH
The pH measures the [H+] while pOH measures [OH-]. You start of by taking the -log of one of the concentration either [H+] or [OH-] and then to solve for the other concentration then use the following equation; pH+pOH=14.

Re: pH and pOH
Dr. Lavelle's lecture went over pH and pOH but additionally watching this video may help. It gives a clear explanation.

Re: pH and pOH
If the ph or pOH is 7, is the solution considered neutral, neither acidic nor neutral?

Re: pH and pOH
If the pH is 7, the pOH has to be 7, and so they would be neutral. Neither the pH or the pOH would be favored in hydrogen ion concentration, so it would be no more acidic than it is basic.
