okay Im not quite sure how to get the Dissociation constant. I have the rest of the values though.

I have 7.00 ml for the first derivative, 6.93ml for the 2nd. It then asks for the average which is 6.97ml

And then it asks for the molarity which is .100M We titrated a unknown acid with .100 NaOH

I have pOH = pKb + log [conjugate acid]/[base]

Im not sure which volume I would use to get the pOH because for some reason the lab instructor told this other guy to devide his average vol by 2 and use that volume to get the pH at that volume. And then plug that into the equation.

Im also not sure which values to use at conjugate acid and base

So can anyone help?
