Why is bromophenol blue rather than phenolphthalein used as an indicator for the antacid titration?

If the solution is brilliant re in alkalies and decolorized by acids it’s the time to used phenolphthalein in analysis as an indicator. The resulting solution is acidic, so you need an indicator that has a pH range that includes pH values below 7.0, like methyl orange, methyl yellow If titrating a strong acid and a weak base and it’s time to use as an indicator called bromophenol blue.
