Chapter 15
When a weak acid and a weak base are dissolved in the same aqueous solution, a buffering effect is observed.

To find the pH in a buffered solution you may use the Hasselbalch equation:
                                           
pH= pKa + log ( base/ acid)
For the titriation of a weak acid with a strong base at equlibrium the pH is greater then 7.
                                      Strong acid and weak base - pH less then 7
                                      Strong acid and a strong base- a pH of 7
                                                     
Q = Ksp
If the Q is greater then Ksp- then a salt will be produced.
