|
The ideal or theoretical result we seek in a titration
|
The equivalence point
|
|
The end which we actually measure, maked by a sudden change in a physical property.
|
The end point
|
|
A compound with a physical property that changes abruptly near the equivalence point.
|
Indicator
|
|
What we use to estimate titration error. you carry out the procedure without the analyte
|
Blank titration
|
|
The difference between the end point and the equivalence point
|
The titration error
|
|
A titrant that is prepared by dissolving a weighed amount of pure reagent in a known volume of solution. reagent is very pure enough to be weighed and used directly
|
Primary standard
|
|
When we prepare the titrant with approximately the desired concentration and use it to titrate an analyte that is a primary standard to discover the concentration of the titrant.
|
Standardization
|
|
Titration in which we add titrant to analyte until the reaction is complete
|
Direct titration
|
|
Titration where we add a known excess of one standard reagent to the analyte. then we titirate the excess reagent with a second standard reagent. you use this when the end point is clearer than that of a direct titiration or when excess of the first reagent is required for complete reaction with the analyte.
|
Back titiration
|
|
Titration where the titrant is measured by mass, not volume.
|
Gravimetric
|
|
List the 8 parts of quality assurance
|
Specifications, selectivity, sensitivity, linearity, accuracy, precision, robustness, range
|
|
States how good the numbers need to be and what precautions are required in the procedure
|
Specifications
|
|
Being able to distinguish the analyte form any other species
|
Selectivity
|
|
The capability of responding reliably and measurably to changes in analyte concentration
|
Sensitivity
|
|
How we a calibration curve follows a straight line
|
Linearity
|
