A 40.0 mL sample of 0.100 M HNO2 is titrated with 0.200 M KOH. Calculate the pH at the equivalence point for the titration of HNO2 and KOH.
I got pH= 11.74.

I estimated the pH and didn't come close to 11 or 12 but I may not have used the same Ka value you did. Most tables in text books don't agree. Post your work and I'll look at it.
Actually, when I did the problem again, I got 8.08.
Is this correct?

Yes, 8. something is right (I think I obtained 8.11 and I used 4E-4 for Ka for HNO2.
