Titrations

Question 1

Equivalence Point

Answer 1

Point when quantity of added titrant is the exact necessary to react with analyte.

Moles titrant = moles analyte

Question 2

End Point

Answer 2

When titration is OBSERVED to be complete

-sudden physical property change

Question 3

Indicator

Answer 3

Compound wiand h a physical property that abruptly changes NEAR the equivalence point

Question 4

Titration Error

Answer 4

Difference between end point and equivalence point

-can be estimated with a blank

Question 5

Blank Titration

Answer 5

Titration performed without the analyte

Question 6

Primary Standard

Answer 6

Titrant prepped by dissolving a weighed amount of pure reagent in a known volume of solution

Question 7

Primary Standard Requirements

Answer 7

99.9% purity

Won’t decompose under normal storage

Be stable when dried

Question 8

Standardization

Answer 8

Process of determining titrant concentration

Question 9

Standard Solution

Answer 9

Titrant that has been standardized

Question 10

Titrant

Answer 10

Reagent solution.

Solution added to analyte

Question 11

Direct Titration

Answer 11

Add titrant to analyte until reaction is complete

Question 12

Indirect Titration

Answer 12

Titration the product of the reaction between the analyte and another reagent

Question 13

Back Titration

Answer 13

Add a known excess of one standard reagent and titrate excess with another standard
