Post-Lab Questions
Directions:
Answer the following questions, show work for all calculations. Work must be shown to receive credit for calculations. All questions are weighted equally.
- What is the difference between the endpoint and the equivalence point in a titration? Are they always the same? Why or why not?
- Report the three molarities from your experimental trials, your average molarity, & the actual molarity below.
Trial 1 ____
Trial 2 ____
Trial 3 ____
Average molarity ___
Actual molarity ____
- A) Are your experimental results considered precise? Justify.
- B) Are your experimental results considered accurate? Justify.
3. Suppose you overshot the endpoint (the solution turned deep pink). Would this cause your calculated molarity of NaOH to be too high or too low? Explain why.
4. Identify one potential error that could have occurred during your experimentation.
5. How would the identified error above have affected your experimentally determined concentration of NaOH.
