Webb1 feb. 2000 · The pH of enhanced-fluidity liquid mixtures at room temperature was determined from the UV/visible absorption spectra of several pH indicators. pH values of methanol/H2O/CO2 mixtures with CO2 proportions as high as 19.2 mol% are reported. The effect of adding buffer to methanol/H2O/CO2 mixtures on pH was also studied.
