Homework Help: chemistry 12

Posted by dan on Tuesday, July 17, 2012 at 7:07pm.

hey i was wondering, i have this question:
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
i know you can t sketch but could you tell me what to do with the "K of 3.0x10^-6" i could sketch the curve without the "K" but i don t know if its an important part for the sketch

Here is a site that sketches MANY titration curves. Look at the left column, third one down from the top. That is a weak acid vs strong base titration curve.
If you know how the strong acid vs strong base looks, for a weak acid/strong base, just start the curve about 3 instead of 1 and slope it a little more.
