Potassium heptaiodobismuthate(4-) (4:1)

Description:

Potassium heptaiodobismuthate(4-) is an inorganic compound characterized by its complex structure, which includes bismuth, iodine, and potassium ions. The compound features bismuth in a +5 oxidation state, coordinated with seven iodine atoms, forming a heptaiodide complex. This results in a negatively charged ion, specifically a bismuthate ion with a formal charge of -4. The potassium ions serve to balance this charge, resulting in a stable ionic compound. Potassium heptaiodobismuthate(4-) is typically encountered as a crystalline solid and is notable for its high iodine content, which contributes to its unique properties. It is often used in various chemical applications, including as a reagent in organic synthesis and in studies involving bismuth compounds. The compound's stability and reactivity can be influenced by factors such as temperature and the presence of other chemical species. Safety precautions should be observed when handling this compound, as iodine can be hazardous in certain forms.

Bismuth potassium iodide

CAS: 41944-01-8

Bismuth potassium iodide is a water-insoluble, inorganic compound. For many years, bismuth potassium iodide, most commonly known world-wide as Dragendorff’s reagent, has been used as a colorimetric agent to detect alkaloids. At present, the Dragendorff’s reagent is composed by bismuth potassium iodide and other additives, and is of great importance in screening natural products. In addition, modified formulations of the Dragendorff’s reagent containing bismuth potassium iodide and different additives are used for the production of surfactants (Raal, 2020).
