Part A.3. the buret is filled with the NaOH titrant
and the initial volume reading is immediately recorded without
waiting the recommended 10-15 seconds. However in part B.1., the
10-15 seconds lapse does occur before the racing is made. Does this
technique error result in an increase, decrease, or have no effect
on the reported percent acetic acid on the vinegar? Expalin

"In the weak acid titration, if you had not prepared your buret
properly and a considerable amount of water was left in it, what
would have been the effect on the calculated value of Ka?"
I generally know that the Ka of an acid remains constant no
matter what, but in this case, the Ka of the weak acid being
titrated can be determined and is equal to the pH at half
equivalence. How would a more dilute strong base...

7a. What is the pH at 0.00 mL of titrant in the titration of
60.00 mL of 0.200 M HA (a generic acid with Ka =
(2.59x10^-5))with 0.400 M NaOH?
7b. What is the pH at 25.00 mL of titrant in the titration of
60.00 mL of 0.200 M HA (a generic acid with Ka =
(2.11x10^-5))with 0.400 M NaOH?

Why do you rinse your buret with KMnO4 solution before filing
it? And, If you had not rinsed your buret with KMnO4 before filling
it the first time and there were some water droplets inside the
buret, what effect would this have on your results? Please explain
in detail.

reach the equivalence point.
b) Predict the effect on the measured equivalence point pH
value.
