How to Interpret Titration Curves
•find the equivalence point
–it is the steepest part of the curve where the pH
rises the fastest
–the equivalence point can be used to determine
the equivalent weight (molar mass) of the acid
•find the mid point
–located in the center of the buffer region
–geometrically halfway between the equivalence
point and the beginning of the titration
–sometimes it is a little more complicated than this
- see the example
–the midpoint determines the pKa of the acid
