:Bismuto
Descrição:
Bismuto, com o símbolo químico Bi e número CAS 7440-69-9, é um metal pós-transição conhecido por suas propriedades únicas. Possui uma densidade relativamente baixa e uma alta massa atômica, tornando-se um dos elementos estáveis mais pesados. Bismuto é caracterizado por sua natureza quebradiça e uma aparência brilhante e prateada com um leve tom rosado. Apresenta baixa condutividade térmica e é um mau condutor de eletricidade em comparação com outros metais. Bismuto tem um alto ponto de fusão e se expande ao solidificar, o que é incomum para metais. Quimicamente, é relativamente inerte, mostrando resistência à oxidação e corrosão, e não reage com água ou ácidos diluídos. Compostos de Bismuto, como o subsalicilato de Bismuto, são usados na medicina, particularmente para problemas gastrointestinais. Além disso, Bismuto é não tóxico em comparação com outros metais pesados, tornando-se uma alternativa mais segura em várias aplicações, incluindo cosméticos e produtos farmacêuticos. Suas propriedades únicas e baixa toxicidade levaram a um aumento do interesse em seu uso em várias aplicações industriais e médicas.

CAS:Produto Controlado<p>Bismuth is a metal that has been used in the treatment of infectious diseases. It is an element with atomic number 83, symbol Bi, and atomic weight 208.904. Bismuth is unique in that it has the highest naturally occurring radioactivity of any element. This property makes bismuth useful for certain medical purposes, such as treating infectious diseases and cancer. Bismuth's coordination geometry can be described as octahedral with a low-dose group consisting of six water molecules and two ligands comprising either citrate or oxalate ions. The ligands bind to bismuth by means of a strong S-S bond in a 2:1 ratio and are coordinated to the metal through oxygen atoms. The redox potential for bismuth is -0.792 V versus standard hydrogen electrode (SHE). It was reported that the reaction mechanism for bismuth is similar to that of other metals, involving oxidation from +3 to +5</p>Fórmula:BiPureza:Min. 95%Cor e Forma:SolidPeso molecular:208.98 g/molRef: 3D-HAA44069
