the reaction of the indicator is HIn+ H20 ->(H30 or H+ )+ In-
if say for instance NaCl were to be added The Na+H20 yields NaOH which you know simply doesnt happen because its ionic so they just float around. Cl part of it would want to react with the H+ so you would get H + Cl -> HCl in the total net reaction which doesn't happen because it is ionic so therefore it simply doesnt happen.
