1. pH & pOH Notes
1. What is the range for the pH scale? What is the range for acidic pH? What pH is neutral? What is always the total of the pH + pOH equal?
2. What does the prefix “p” in the terms pH or pOH mean? What is the definition of pH?

2. Steps To Finding pH & pOH
Examine the formula of the compound. If the compound has H+ in the formula then that solution is an acid. This will give you the pH If the compound has OH in it then that compound is a base and will give you the pO
Next write the concentration (Molarity) as a “power of ten as 1 x 10-X X = # of decimal places.
 The positive number for X will be the pH if an acid or pOH if a base. Find the other by subtracting the one you found from 14. pH + pOH = 14.

3. 4. Determine the pH and pOH and pOH of the following:
M LiOH
 0.001 M HBr
M HF
  M KOH
 0.001 M HCl

4.  pH = 5.4 then pOH = _________
Is this acidic or basic? ______________
B. pOH = 2.7 then pH = __________
Is this acidic or basic? ____________
