20.0mL of 0.15mol/L HNO3(aq) is being added to 17mL of 0.23mol/L NH3(aq). What is the equivalence point?
I'm not sure how to go about solving this, although I've certainly toyed with it a lot.
What I've gotten is:
HNO3 (aq) + NH4OH (aq) --> H2O (l) + NH4NO3 (aq)
[NH4OH] = 3.9 x 10^-3
(0.15mol/L)x = 3.9 x 10^-3
x = 0.026
26mL of HNO3 is not available in this reaction, so the equivalence point is not reached.
Which I know is wrong because the weak base won't dissociate 100% like I'm assuming it will in my calculations, I really have no idea what to do here, I'd really appreciate a push in the right direction!
