<div>I’m completely lost on how to find the Ka and pKa of the
buffer solution from last week’s lab. I’ve read the textbook
chapter and looked online, but nothing I've found has been
helpful, as it seems that I need molar mass to find the
concentration so I can make the calculations, but I don’t have
that information. Is there any way you could explain how to
find the Ka and pKa with what we have, or give us a hint to
lead us in the right direction? Thank you!</div>

When you recombined unknown that you titrated with the half you kept
separate and measured the pH you also measured the pKa of the acid.<br>
