Practice Questions
Test your understanding with targeted questions
Calculate the mean of the equivalence volumes: 25.05 mL, 25.00 mL, and 25.10 mL.
💡 Hint: Add the volumes together and divide by the number of measurements.
If a titration requires 30.00 mL of NaOH, what is the volume in liters?
💡 Hint: Remember that 1 L = 1000 mL.

Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Ensure to consider all uncertainties involved.
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.
💡 Hint: Think about equipment maintenance and calibration frequency.
