Standardizing a Base by Titration Digital Badge

Contact Information

The Standardizing a Base by Titration badge is a competency badge offered by the Department of Chemistry and Biochemistry. Content and skills are learned and demonstrated through academic coursework in an analytical chemistry laboratory setting.

Earning Criteria

Participants earning this badge are required to titrate a primary standard to determine its molarity and confirm the precision and accuracy of their data within established tolerance levels.

Competencies Demonstrated

1. Use an analytical balance to accurately weigh a primary standard.
2. Perform a titration for at least three trials, or until a precision of 1% relative standard deviation is achieved.
3. Calculate the concentration of base.
4. Solve for the sample standard deviation, average, and percent relative standard deviation.
5. Report final values to the correct number of significant figures.
6. Calculate the percent error for the average concentration. This percent error must be less than or equal to 10%. If this benchmark is not met, the student will have another opportunity to collect more data if they choose.
7. Compare the standard deviation to the uncertainty of the concentration.
8. Evaluate in a written statement if the results are both accurate and precise.
