8.7 Titration

Question 1

Titration

Answer 1

Addition of precise volumes of a solution in a burette to a measured volume of a sample solution: often used to determine the concentration of a substance in the sample

Question 2

Sample

Answer 2

Solution being analyzed in a titration

Question 3

Titrant

Answer 3

Solution in a burette during a titration

Question 4

Burette

Answer 4

Calibrated tube used to deliver variable known volumes of a liquid during a titration

Question 5

Standard solution

Answer 5

Solution whose concentration is accurately/precisely known

Question 6

Primary standard

Answer 6

Highly pure/stable chemical used to determine the precise concentration of acids or bases

Question 7

Equivalence point

Answer 7

Point in titration when neutralization is complete

Question 8

Endpoint

Answer 8

Point in titration at which sharp change in a measurable and characteristic property occurs (ex. colour change in acid-base indicator)

Question 9

pH curve

Answer 9

Graph of pH plotted against volume of titrant added in an acid-base titration: titration curve
