This paper is used for the determination of fluoride ions and gaseous hydrogen fluoride (H2 F2 ). The pinkish-red paper turns yellowish-white in the presence of fluorides. Substantial amounts of chlorates, bromates and sulphates cause white discolorations of the paper. These interferences are readily circumvented.
