mental data for all buffer systems. For exam-ple, the average percent deviation in the measured buffer solubility and that pre-dicted by equation 4 for the ammonium phosphate (pH 3.0) buffer system was 6.3%, 7.4%, and 5.6% for methanol, acetonitrile, and tetrahydrofuran cosolvents, respectively. Similar or lower errors using equation 4 were seen for the other buffer systems. In ï¬tting the experimental data to equa-tions 1â5, we assumed that each buffer is insoluble (y 0 mM) in pure organic media (100% B).
