Arrhenius Acid
|
Produces H30+, hydronium ion in aqueous solutions
|
|
Arrhenius Base
|
Produces OH- in aqueous solutions
|
|
Bronsted-Lowery Acid
|
H+ donor
|
|
Bronsted- Lowery Base
|
H+ acceptor
|
|
Salt
|
an ionic compound
|
|
Autoprotolysis
|
the reaction of a neutral solvent, in which two molecules of the same species transfer a proton from one to the other thereby producing ions
|
|
Protic Solvents
|
have a reactive H+
|
|
Aprotic Solvents
|
have no reactive H+
|
|
Polyprotic Acids and Bases
|
can donate or accept more than one proton
|
|
Volumetric Analysis
|
a technique in which the volume of material needed to react with the analyte is measured.
|
|
Titration
|
a procedure in which one substance the titrant is carefully added to another analyte until complete reaction has occurred. The quantity of titrant required for complete reaction tells how much analyte is present.
|
|
Equivalence Point
|
In a titration when all analyte has reacted and there is no excess titrant.
|
|
End point
|
When a titration is stopped. Recognized by a sudden change in a physical property of the solution.
|
|
Indicator
|
a compound with a physical property (usually color) that changes abruptly near the equivalence point
|
|
Titration Error
|
the difference between the end point and the equivalence point.
|
|
Blank Titration
|
a titration is carried out without analyte to estimate titration error
|
|
Primary Standard
|
a solution that can be readily obtained in high
purity and low cost. |
|
Secondary Standard
|
a solution whose makeup is determined by reference to a primary standard
