Gran plot

A graph used to find the end point of a titration. The slope of the linear portion of the graph is related to the dissociation constant of the acid.


Hammett acidity function

The acidity of a solvent that protonates the weak base, B. For dilute aqueous solutions, H approaches pH.



A compound having a physical property (usually color) that changes abruptly near the equivalence point of a chemical reaction.


indicator error

Difference between the indicator endpoint of a titration and the true equivalence point.


Kjeldahl nitrogen alaysis

Procedure for the analysis of nitrogen in organic compounds.


leveling effect

The strongest acid that can exist in solution is the protonated form of the solvent. A stronger acid will donate its proton to the solvent and be leveled to the acid strength of the protonated solvent. Similarly, the strongest base that can exist in a solvent is the deprotonated form of the solvent.


transition range

For an acid-base indicator, the pH range over which the color change occurs. For a redox indicator, the potential range over which the color change occurs.
