The pH buffers used to calibrate the pH meter were each 0.5 pH units high (4.5 and 7.5 rather than 4.0 and 7.0 respectively). You decided to take the pH after each addition of 5.0 mL of NaOH rather than after every 0.5 mL during the neutralization of your acid sample. 1. pKa would be unchanged. 2. pKa would be too high.

While using the Half Volume method, your solution was dark pink (you overshot the endpoint) and you added the unreacted acid to this solution.

Derive an equation similar to the Henderson–Hasselbalch equation for a buffer composed of a weak base and its conjugate acid. Instead of relating pH to pKa and the relative concentrations of an acid and its conjugate base (as the Henderson– Hasselbalch equation does), the equation should relate pOH to pKa and the relative concentrations of a base and its conjugate acid.
