4. a student needs to prepare a buffer solution with a ph of 5.59. assuming a pka of 4.54,
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.
int vol-
hint: use ph = pka + log ([b-1/[hb]) or, if concentrations are the same,
ph = pka + log (volume of oh-/ (volume of hb - volume of oh-) )
