Ph of the ionic liquid
WebFeb 1, 2024 · The main parameter for the characterization of micelle forming ionic liquids is the critical micellar concentration ( cmc ), which corresponds to the threshold concentration at which the surfactant starts forming larger aggregates consisting of several dozen to hundreds of molecules. WebA buffer is effective at ± one pH units from the pK of the buffering ion, giving some flexibility in optimizing the mobile phase. Acetate, for example, has a pKa of 4.8 and buffers from pH 3.8 to 5.8. Formate is more acidic and buffers from pH 2.8 to 4.8. There are additional buffer choices if acidic analytes would be not be ionizable at lower pH.
