A student needs to prepare a buffer solution with a pH of 4.60. Assuming a pK a of 4.12, how many mL of 0.1 M B minus would need to be added to 20.0 mL of 0.1 M HB 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 B minus / Volume of HB)
