Description
The “Titration Olympics” is the capstone experiment at the end of the Spring semester’s Advanced Chemistry Acid-Base-Buffer unit. In this lab exercise, students compete to determine the concentration of an unknown acid solution using a sodium hydroxide solution they prepare and standardize using KHP. The winner is determined using a rubric that accounts for (a) overall lab time, (b) preparation and general lab technique, (c) data table, (d) quality of the phenolphthalein endpoints, (e) accuracy of the unknown acid’s molarity, (f) use of significant figures, and (g) clean up skills. Students enjoy the competitive spirit of the experiment and realize the importance of meticulous technique to produce an effective and efficient titration. You will perform the student activity using the lab handout in this session. Challenge yourself to outperform our students!
