Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

100%

A student needs to prepare a buffer solution with a pH of 5.52. Assuming a pK₂ of 4.07, how many mL of
0.1 M B would need to be added to 25.0 mL of 0.1 M HB prepare this buffer?
Please include a proper (abbreviated) unit.
HINT: Use pH = pK₂ + log ([B minus]/[HB]) or, if concentrations are the same,
pH = pka + log (Volume of B minus/ Volume of HB)
