Descrição geral

Também conhecido como cloromagnesita, o cloreto de magnésio é um sólido cristalino incolor. É de natureza muito higroscópica. É solúvel em água e álcool. Pode ser preparado pelo aquecimento de cristais de cloreto de magnésio hidratado em uma corrente de cloreto de hidrogênio seco ou por aquecimento de cloreto de magnésio-amônio. O cloreto de magnésio anidro se cristaliza a partir de cloreto de magnésio hexa-hidratado em lamínulas. Ele é eletricamente condutor. A estrutura cristalina de MgCl2 é semelhante a camadas. A estrutura é cúbica e compacta com camadas alternadas de furos em formato octaédrico preenchidos com íons de Mg2+.

Atenção

O aspecto de manchas de cor cinza/preta não deve afetar o uso.
