Re: Titrations
To calculate the pH at the halfway point, use the shortcut: pH = pKa.
To determine the volume of titrant added to get to the halfway point, use the equation M(acid)V(acid)=M(base)V(base) (because at the endpoint, moles of acid equals moles of base). The unknown volume that you are solving for is the volume at the endpoint. If you half this volume, you have now gotten the volume of titrant added at the halfway point.
