Physical and Chemical Properties | Bismuth subnitrate also known as bismuth oxynitrate, bismuth subnitrate. Formula 4 BiNO3(OH)2 · BiO(OH), molecular weight 1461.99. White crystalline powder or pearlescent scales. Odorless and tasteless. Relative density of 4.928, melting point of 250 deg C (decomposition),260 deg C to lose water. Slight deliquescence. See Light stability, such as mixed with silver, plus high temperature that yellowing and melting into oxides. Partial decomposition at 100 ° C, loss of water and nitric acid, insoluble in water and alcohol, soluble in hydrochloric acid, nitric acid and dilute sulfuric acid, water suspension was weakly acidic. Bismuth nitrate and water containing five molecules of crystal water were ground, ammonia was added, impurities were removed, and dried. Used as chromatographic analysis reagents, and used in the pharmaceutical industry, testing sugar and alkaloids, bismuth powder and antiseptic powder. |

white powder. Odorless and tasteless. Slight deliquescence. Soluble in dilute hydrochloric acid, nitric acid, dilute sulfuric acid, insoluble in water, ethanol and glycerol. Heat decomposition of bismuth oxide and nitrogen oxide.
The crystalline bismuth nitrate is made into a suspension solution, which is adjusted by adding a refined sodium carbonate solution or ammonia water, and the reaction is continuously stirred, and the reaction product is filtered, washed and dried.
It is used to test sugars and alkaloids in clinical examination, and is used as a neutralizing gastric acid and astringent, treating gastric and duodenal ulcer and Diarrhea, etc. It is also a raw material for the manufacture of bismuth salt and ceramic glaze.
bismuth nitrate is a strong oxide, strong corrosive, not to contact with the skin, pay attention to protect the eyes. Staff should be well protected. Cotton fabrics and wood products exposed to nitrate shall not be close to the heat source to prevent spontaneous combustion caused by heating and fire.
