11. The degree of titration is useful to standardize the titration curves.
Acid-Base Titrations
The degree of titration:
The degree of titration is useful to standardize the titration curves.

13. General features of titration curves derived from logarithmic acid-base diagrams:
Dilution during titration is neglected.
Only specific points are transcribed from the acid-base diagram to the titration diagram. (Complete titration diagrams can easily be drawn with the free program which displays pH as function of added volume of titrator.
