how would i sketch a pH curve for the titration of40.00mL of 0.100 M hydrazine H2NNH2(aq) having a Kb of 3.0x10^-6 by 0.100M HCIO4(aq) ?
We can't draw the curves on this board; however, I found one drawn on the web. Go to this site and scroll about 1/3 down to "strong acid + weak base". There is a titration curve that starts with NH3 and is titrated with HCl. That will be essentially the same for your weak base and strong acid.
thank you this should help!
