Bismuth oxide nitrate ( Bismutum subnitricum ) is a chemical compound from the group of nitrates .
Extraction and presentation
Bismuth oxide nitrate can be obtained from bismuth (III) nitrate hydrate by heating or dissolving in pure water. In contrast to other nitrates, it is only sparingly soluble in water.
use
Bismuth oxynitrate place (like other bismuth compounds ) as reserve medication for stomach - intestinal ulcers use, since it is the healing of ulcers and the eradication of the pathogen Helicobacter pylori promotes. It is used as a so-called quadruple therapy, a combination therapy consisting of a proton pump inhibitor and a classic bismuth triple therapy (bismuth salt, tetracycline , metronidazole ).
It's also a component of Dragendorff's reagent , which is made up of bismuth oxide nitrate, tartaric acid, and potassium iodide .
