Question
**Buffer Preparation Problem**

A student needs to prepare a buffer solution with a pH of 5.86. Assuming a pKₐ of 4.30, how many mL of 0.1 M NaOH would need to be added to 24.0 mL of 0.1 M HB to prepare this buffer?

Please include a proper (abbreviated) unit.

**HINT:** Use pH = pKₐ + log ([B⁻]/[HB]) or, if concentrations are the same,

pH = pKₐ + log (Volume of OH⁻ / (Volume of HB minus Volume of OH⁻))
