Consider the reaction involving indicator if it produce H+?

[Chem_Mod]

Question: Do we consider the reaction involving an indicator, which produces hydronium ions, as insignificant when considering the change in the concentration of hydronium ions?

[Chem_Mod]

Answer: Yes, even though the indicators do have an effect on the hydronium concentration, indicators are used in minute concentrations so that their effect is negligible. At the same time, their colors are still intense enough to be observed at very low concentration.
