1

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.

2

Hammett acidity function

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

3

indicator

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

4

indicator error

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

5

Kjeldahl nitrogen alaysis

Procedure for the analysis of nitrogen in organic compounds.

6

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.

7

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.
