Calculate the volume at which pH = pKa if 30.00mL of weak acid with a concentration of 0.0955M is titrated
against a strong base with a concentration of 0.1233M.

1. Caroline

.0955molacid*.030L weak acid= .002865 mol acid/.1233 mol base= .02325 L base/2=11.62mL

I got confused once I found my moles of acid, did I finish it correctly?

You are right on the money!

Why did you divide your L by 2?
