pH and pOH are both logarithmic scales measuring the acidity (or basicness) of a solution. pH is based on the amount of H+ (hydrogen ions), and pOH is based on the amount of OH- (hydroxide ions) in the solution.
You can calculate pH if you know the H+ activity: pH = - log10 (H+)
pOH is calculated the same way, except with OH- instead of the H+ ions.
pOH is also equal to 14 - pH. This is because the pH and pOH scales go from 0 to 14.
A solution that is very acidic will have a low pH number and a high pOH number.
Conversely, a very basic solution will have a low pOH and a high pH.
Water is a neutral solution and has a pH and pOH of 7, which is in the middle.

I don't understand 'PH'!!!! If you mean 'pH' , then it is a logarithmic measure of the hydrogen ion concentration.
Note the symbol is 'pH'. not 'PH'.
