Bismuth subcitrate potassium is a salt of bismuth (Bi 3+), potassium (K +) and citrate (C 6 H 4 O 4− 7) in a molar ratio of about 1:5:2, with 3 moles of water. It contains about 25.6% (mass percent) bismuth, which is the active moiety, and 22.9% potassium. [3] [4] Other sources give somewhat different ratios of the constituents.
