Chemistry- Dr.Bob

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.

When I did this problem again, I got
pH= 8.08.

Is this close to your answer?

Dr.Bob:
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.
