Question

A student needs to prepare a buffer solution with a pH of 5.59. Assuming a pK a of 4.54, how many mL of 0.1 M N a O H 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 = pK a + log ([B minus]/[HB]) or, if concentrations are the same,

pH = pK a + log (Volume of O H minus/ (Volume of HB - Volume of O H minus)
