ich is the best colored indicator to use in the titration of 0.1MCH3CO2H(aq) with NaOH(aq) ? Why? (Ka of CH3CO2H=1.8E5,Kb of CH3CO2=5.6E10) Phenolphthalein. The pKa of CH3CO2and the pKb of the indicator are similar. Phenolphthalein. The pH at the equivalence point is near the pKa of the indicator. Bromthymol Blue. The pH at the equivalence point is 7.0 . Bromcresol Green. The equivalence point for a weak acid titration occurs at low pH. Bromcresol Green. The pKa of CH3CO2H and the pKa of the indicator are similar
