Question

Match each term below with its definition or description.

1 The point in a titration when the added amount of standard reagent is equal to the amount of analyte being titrated. 11) End Point

2 The analyte is titrated with the standard reagent and the volume of standard solution required to complete the reaction is measured. 12) Indicator

3 A reagent that is pure and stable, which can be used directly after weighing. 13) Direct Titration

4 The analyte that is being analyzed in the titration. 14) Back Titration

5 Standard reagent is added in excess to ensure complete reaction with the analyte. The excess reagent is then titrated with a second standard reagent. 15) Indirect Titration

6 A solution, whose concentration is known, often made from a reagent of known purity. 16) Primary Standard

7 The standard reagent of known concentration that is added from a buret to the analyte solution. 17) Standard Solution

8 The analyte does not react directly with the titrant so it is converted to another form which will react with the titrant. 18) Titrand

9 The point in a titration when a change in the analyte solution is observed, indicating equivalency. 19) Equivalence Point

10 It is added to the analyte solution and aids in the observation of the completion of the reaction. 20) Titrant

Explanation / Answer

1) The point in a titration when the added amount of standard reagent is equal to the amount of analyte being titrated. 19) Equivalence Point
