Bismuth Basic Nitrate

Sodium bismuthate (oxidation of manganese) heat 20 parts of NaOH nearly to redness in an iron or nickel crucible, and add slowly 10 parts of basic bismuth nitrate which has been previously dried. Add 2 parts of sodium peroxide, and pour the brownish-yellow fused mass on an iron plate to cool. When cold break up in a mortar, extract with water, and collect on an asbestos filter. 

Bismuth subnitrate [1304-85-4] (basic bismuth nitrate) can be prepared by the partial hydrolysis of the normal nitrate with boiling water. It has been used as an antacid and in combination with iodoform as a wound dressing (183). Taken internally, the subnitrate may cause fatal nitrite poisoning because of the reduction of the nitrate ion by intestinal bacteria. 

The Dragendorjf reagent is available in different compositions, and it mainly stains nitrogen-containing compounds, producing colored zones on a white background. For solntion a 1.7 g of basic bismuth nitrate and 20 g of tartaric acid are dissolved in 80 ml of water. For solution b 16 g of potassium iodide are dissolved in 40 ml of water. The final spray reagent is mixed from solution a and b in the...

Bismuth oxychloride (BiOCl) is a colorless fine powder, which melts at 232°C and boils at 447°C. It is practically insoluble in water and alcohols, but readily soluble in hydrochloric acid and nitric acid. Above 570°C, it liberates BiCb to be transformed into a Bi405Cl3 compound. Among bismuth oxyha-lides, only the oxychloride is available commercially at a cost of US 30.00 ( 7500) for a sample of 99% purity and US 98.60 ( 24 400) for a sample of 99.99% purity per 50 g. However, other oxyhalides can readily be prepared by partial hydrolysis of trivalent bismuth halides or by the interaction of basic bismuth nitrate (BiO(N03)) with the corresponding sodium halide in aqueous...

Bismuth chloride oxide (BiClO basic bismuth chloride or bismuth oxychloride) is a tetragonal compoimd consisting of alternating sheets of O and Cl atoms with Bi atoms in between. It is generally synthesised from a basic bismuth nitrate solntion and sodium chloride or by dilution of a concentrated aqneous bismuth chloride solution (MacIntyre, 1992). 

The chloride was also sold as blanc de Perle or pearl white when it was prepared by precipitation of aqneous bismutii nitrate with hydrochloric acid and blanc cTEspagm, where aqueous bismuth nitrate was mixed with brine Colour Index, 1971). Other terms apparently associated with this compound are flake white and bismuth white (qq.v.). The Colour Index identifies two white bismuth compounds used as pigments Cl 77163/Pigment White 14, which is listed as bismuth chloride oxide (BiClO), and Cl 77169/Pigment White 17, which is described as basic bismuth nitrate . 

Reagents Solution I Basic bismuth nitrate (850 mg) is dissolved in 10 ml of acetic acid and 40 ml of water. Solution II Potassium iodide (8 g) is dissolved in 20 ml of water. The two solutions are mixed and can be kept in brown bottles for several months. Before use 10 ml of this stock solution is diluted with 20 ml of acetic acid and 100 ml of water. 

Reagents Solution A Dissolve 1.7 g basic bismuth nitrate or bismuth nitrate pen-tahydrate in 20 mL glacial acetic acid. Make up to 100 mL with water. Solution B Dissolve 40 g KI in 100 mL H2O. Test Solution Mix 10 mL each of Solutions A and B with 20 mL acetic acid and 60 mL water. Add 50 mL 20% BaCl2 solution and store in a brown bottle. For optimal reproducibility, the combined solution should not be more than two days old. 

KBil solution Dissolve 1.7g basic bismuth nitrate or bismuth nitrate pentahydrate in 20 mL glacial acetic acid and 80 mL distilled water. Mix with a solution of 65 g potassium iodide in 200 mL H2O, add 200 mL acetic acid, and dilute to 1 L with water. 

Procedure Sedimetric Procedure for Determination of Nonionic Surfactants (58) Reagent Dissolve 1.7 g basic bismuth nitrate or bismuth nitrate pentahydrate with 20 mL glacial acetic acid and dilute with water. Separately, dissolve 40 g KI in water. Combine the two solutions in a 1-L volumetric flask, add 200 mL glacial acetic acid, and dilute to the mark with water. This is the stock solution, which is stable for only 2 days. Prepare a mixed reagent shortly before beginning the analysis by mixing 100 mL of this stock solution with 50 mL 20% BaCl2 solution. Store in an amber bottle.
