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. WebThus, in acidic solution, Bi can be effectively titrated with a chelating agent in the presence of alkaline earth metals. A mixture of bismuth and lead ions can be successfully titrated by first titrating the bismuth at pH 2 with xylenol orange as indicator, and then adding hexamine to raise the pH to about 5, and titrating the lead. 25
