pH and pOH
the red is acidic and the blue is basic
What does a pH and pOH scale measure?
The pH and pOH scales measure how acidic or basic a substance is and they range from 0 to 14.

Calculations
these are the "need to know" formulas (note that "log" is a function on calculator and "2nd log" is also a function on a calculator)
*note that if you are given the molarity of an acid, the molarity is the concentration, and the concentration is the measure of the [H+]* BUT *note that if you are given the molarity of a base, the molarity is the concentration, and the concentration is the measure of the [OH-]* |
