Hey guys i only have this question left on my review and i just can't fingure it out!
Sketch a pH curve for the titration of 40.00mL of 0.100 M hydrazine, H2NNH2, having a K of 3.0x10^6 by 0.100 M HCIO4
a) what combination of acidebase titration is this? (SASB; SAWB; or SBWA)
b)Identify and buffering regions.
c) What is the predicted apporximate pH at equivalence point?
d) What is the voliume of HCIO4 added at the equivalence point?
e) How many "quantitative" or "stoichiometric" reactions are taking place?
f) Write an equation for any hydrolysis reaction taking place.
G) suggest a suitable indicator for this titration. Explain

We can't draw pictures on the board; however, here is a site that gives graphs of titration curves. The curve you want is a weak base/strong acid curve (HClO4 is a strong acid/hydrazine is a weak base).

that is helpful, i just don't get how to get the graph right, mine went up, how do i get the numbers and plot the graph correct?
