Aqueous acetic acid as a medium for the facile use of ferroin as redox indicator in the presence of perchloric acid.
Ferroin cannot be used as an indicator in perchloric acid medium because of precipitation of ferroin perchlorate. There is no precipitation, however, if the solution contains 30%(v/v) of acetic acid.
