Question
Match each term below with its definition or description. The point in a titration when the added amount of standard reagent is equal to the amount of analyte being titrated. The analyte is titrated with the standard reagent and the volume of standard solution required to complete the reaction is measured. A reagent that is pure and stable, which can be used directly after weighing. The analyte that is being analyzed in the titration. Standard reagent is added in excess to ensure complete reaction with the analytic. The excess reagent is then titrated with a second standard reagent. A solution, whose concentration is known, often made from a reagent of known purity. The standard reagent of known concentration that is added from a buret to the analyte solution. The analyte does not react directly with the titrant so it is converted to another form which will react with the titrant. The point in a titration when a change in the analytic solution is observed, indicating equivalency. It is added to the analytic solution and aids in the observation of the completion of the reaction.Explanation / Answer
Note: Numbers are given to the entries on left hand side and their match is given in bold next to each entry.
1) The point in titration when the added amount of standard reagent is equal to the analyte being titrated is known as The Equivalence point of the titration.
2) The analyte is titrated withstandard reagent and the volume of standard solution required to complete the reaction is measured is known as Direct titration .
3) The reagent that is pure and stable and can be used directly after weighing is known as Primary standard.
4) The analyte that is being analysd in titratonis known as Titrand.
5) The standard reagent is added in excess to ensure complete reaction with analyte the excess is the titrated with anathor standard is known as Back titration.
Back titration is the titration done in reverse way. Instead of original sample, the excess of known standard is added to the solution and this excess is allow ti titrate. It is useful and often easier way to find out end point of titration than normal.
6) The solution whose concentration is known and it is often made from the reagent of known purity (and is stable in environmental condition i.e. not hygroscopic, not getting oxidised or reduced) is known as Standard solution.
Concentration of primary solution does not changes for long time.
7) The standard reagent of known concentration that is added from burette to analyte solution is known as Titrant.
8) The analyte does not react directly to titrant so it is converted to anathor form which will react with titrant this kind of titration is termed as Indirect Titration.
9) The point in a titration when a change in the analyte solution is observed, indicating equivalency . is known as the End point of titration.
10) It is added to the analyte solution and aids in the observation of the completion of the reaction is known as an Indicator.
