Question

1. Explain the difference between the equivalence point and the endpoint in an acid/base titration. (2 pts) 2. If the endpoint in the titration of the HCl with the NaOH standard solution is overshot (too pink), what effect does this have on the calculated molar concentration of the HCl solution? (2 pts) 3. Why is it important for the buret to be conditioned before use? (2 pts) 4. Why are air bubbles in the buret tip a source of error in a titration experiment? How do you remove air bubbles from the buret tip? (2 pts)
