The original De-Nol formulation was a colloidal suspension in ammonia water and had the very pungent odor.

Example of forms of bismuth. This page introduces you to the idea of a reversible reaction. The most widely used forms of bismuth in use for gastroenterology at the time of the discovery of H pylori were bismuth subnitrate subsalicylate and subcitrate. Cest le cinquième et dernier élément du groupe des pnictogènes.

In the 1970s Gist-Brocades introduced a proprietary preparation of colloidal bismuth subcitrate De-Nol as an antiulcer therapy. Bismuth oxide is used as a yellow pigment for cosmetics and paints while many cosmetics including lipsticks eyeshadow and nail polish contain bismuth oxychloride a pearly powder which makes these products shine. It is more deleterious than Pb or.

Thus bismuth is extremely brittle and is reluctant to form mixed crystals with cadmium which has HCP structure. Compounds of Bismuth have diverse uses ranging from cosmetics to pharmaceuticals and medicine to nuclear energy. With Pb it forms a eutectic at 55 at- Bi with a melting point of 125C.

With Sn it forms a eutectic at 43 at- Bi with a melting point of 139C. Bismuth forms trivalent and pentavalent compounds the trivalent ones being more common. The first BFO sample was synthesized in the late 1950s 605 and the crystal structure was characterized a few years later 764.

It is located in Group V of the Periodic Table with nitrogen phosphorus arsenic and antimony. Bismuth does not form solid solutions with most technical metals Al Cu Fe Mg it is nearly insoluble in these metals in the solid state. It is white amorphous finely crystalline powder.

Bi 2 S 3. Thus it comesfor examplefrom tungsten ores in South Korea lead ores in Mexico copper ores in Bolivia and both lead and copper ores in Japan. What is a reversible reaction.
