Characteristic Reactions of Bismuth (Bi³⁺) - Chemistry LibreTexts

WebAug 15, 2024 · According to periodic trends, bismuth is the strongest reducing agent since it has an electronegativity value of 1.9 which is the same as Antimony but it has a lower ionization energy of 703 kJ/mol which means it is more likely to get oxidized. True; bismuth is the only metallic element of Group 15. WebBismuth (atomic symbol: Bi, atomic number: 83) is a Block P, Group 15, Period 6 … When red-hot, it reacts with water to make bismuth (III) oxide. [32] 2 Bi + 3 H 2 O → Bi 2 O 3 + 3 H 2 It reacts with fluorine to make bismuth (V) fluoride at 500 °C or bismuth (III) fluoride at lower temperatures (typically from Bi melts); with other halogens it yields only bismuth (III) halides. See more Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic See more Bismuth metal has been known since ancient times and it was one of the first 10 metals to have been discovered. The name bismuth dates to around 1665 and is of uncertain etymology. The name possibly comes from obsolete German Bismuth, Wismut, … See more Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are … See more Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials. In the United States, for example, 733 tonnes of bismuth were consumed in 2016, of which 70% went into chemicals … See more Bismuth compounds account for about half the global production of bismuth. They are used in cosmetics; pigments; and a few pharmaceuticals, notably bismuth subsalicylate, used to treat diarrhea.
