Indirect titration is suitable for cases where indicator
blocking occurs. Indicator blocking happens when
the metal does not precipitate out of the solution.
the metal indicator complex is too strong that the metal does
not dissociate from the indicator when EDTA is added.
the metal-EDTA complex is too strong that the metal does not
dissociate from EDTA when the indicator is added.
none of the choices
the indicator reacts with EDTA which prohibits the formation of
metal complexes.
