pH and pOH

Now imma do a taboo and use something I already used in this unit, but I gotta, go HERE to see more on pH and pOH, again, as a refresher, but after you read everything. And since I like to use lots of videos, HERE'S another guy explaining it.

But anyway, pH is the measure of power of H+ in the mixture. It is on a scale of 1 to 14, normally, with 7 being a perfect neutral, and is pure water. pOH is the same, but has the power of OH- in the mixture. Oh, and both are inverse, so a low pH is a high Acid power, and a low pOH is a high Base power. With these powers being ten times more acidic or basic than the next: ex. a pH of 2 is 100 times more acidic than a pH of 4.
To get a visual of how the scale works, put your gaze here:

To find these magical number you take the - Logarithm base 10 to the moles of H+(or OH- depending on what your trying to find) to get the pH, and to derive the pOH from pH, or vice versa, you take 14 and subtract the one you have. Poof, you have what you were looking for.
