WebMar 15, 1996 · Bismuth titrated in the presence of DFB exhibits a sharp inflection at 2.0 mol titrant per mol bismuth and then another at 3.0 (see Fig. 1 ). In the absence of ligand, the first inflection occurs roughly at 2.5. Thereafter, a white precipitate forms. When DFB is present, a precipitate only appears after a titrant ratio of 3.0. WebThe principal chemical application of bismuth is in the form of bismuth phosphomolybdate (BiPMo 12 O 40 ), which is an effective catalyst for the air oxidation of propylene and ammonia to acrylonitrile. The latter is used to make acrylic fibres, paints, and plastics. Pharmaceutical uses of bismuth have been practiced for centuries.
