Question

Identify possible errors that could affect the quality of your titration and calculations.

Select one or more:

O Some KHP is spilled from the weigh boat as the analyte solution is prepared.

O When recording measurements from the buret, volumes are read from the meniscus.

O The titrant volume is incorrectly calculated and recorded in the lab notebook.

O The acid solution is titrated in a 250 mL beaker rather than a 250 mL flask.

O Titrant is added beyond the light pink endpoint of the analyte solution.

Answer 1

Errors in titration may include spilling the reagent, incorrect recording of volumes, using improper apparatus, or adding excess titrant.

option e is the correct

Step-by-step explanation:

Possible errors that could affect the quality of your titration and calculations include:

• Spilling some KHP from the weigh boat while preparing the analyte solution.
• Incorrectly recording the titrant volume in the lab notebook.
• Using a 250 mL beaker instead of a 250 mL flask for the acid solution, which could affect the mixing and result in an incomplete reaction.
• Adding titrant beyond the light pink endpoint, leading to an overestimation of the volume of titrant needed.

It is also mentioned that when recording measurements from the burette, volumes should be read at the meniscus level, which is correct and not an error.
