How would your results be different if the unknown HCl solution in part 2 was me

Question

How would your results be different if the unknown HCl solution in part 2 was measure -graduated cylinder instead of a volumetric pipet? For both parts of the experiment, why was it necessary to perform each titration three times? Why was it important to continue the titration past the equivalence point? Why was it important to control the drops from the buret when using the once Why would a steady stream cause you to start over? How would your results be different if you placed the unknown HCl solution in the tot-placed the standardized NaOH solution in the beaker? How does the precision required for Part 1 differ from that of Part 2? what are some sources of errors that are associated with both parts of the can you prevent these errors?

Explanation / Answer

Q5.

HCl measurements will be MORE precise, since volumetric pipets are mor precise than graduated cylinders

Q6.

it is important in order to get an average, i.e. understand the variability (standard deviation) of the pocess/student

a. If we continue past the equivalence point, we ensure ALL acid+base reacts

b. In order to account for the total volume

Q7.

Should not change, since the amounts are the same...

Q8 and 9

Impossible to solve fr P1 and P2 (not shown)
