Question 1.
Calculate the mean of the equivalence volumes: 25.05 mL, 25.00 mL, and 25.10 mL.
Show hintHide hint
Add the volumes together and divide by the number of measurements.
Question 2.
If a titration requires 30.00 mL of NaOH, what is the volume in liters?
Show hintHide hint
Remember that 1 L = 1000 mL.
3Question 3.
What is the equivalence volume?
- The volume at which the endpoint is reached
- The total volume used
- The initial volume of titrant
Show hintHide hint
Think about when the chemical reaction is complete.
4Question 4.
Is uncertainty found in all measurements?
- True
- False
Show hintHide hint
Reflect on the precision of your measuring tools.
Question 5.
A student performs titrations leading to obtained equivalence volumes of 25.12 mL, 25.09 mL, and 25.10 mL. If their titrant solution concentration is 0.1000 M, calculate the concentration of HCl, including uncertainty.
Show hintHide hint
Ensure to consider all uncertainties involved.
Question 6.
Consider a titration where the equivalence point is achieved at volumes showing high deviation due to pipette calibration error. Propose a protocol to reduce uncertainty in these measurements.
Show hintHide hint
Think about equipment maintenance and calibration frequency.
