Bismuth subnitrate

Nylander s solution (detection of glucose) dissolve 40 g of rochelle salt and 20 g of bismuth subnitrate in 1000 mL of an 8% NaOH solution. 

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.

Bismuth subnitrate (BiNO ) is used in the cosmetics industry and to make ceramic and enamel glazes. 

Bismuth oxycarbonate is prepared by adding sodium carbonate to a suspension of bismuth subnitrate in water. 

Bismuth trioxide is commercially made from bismuth subnitrate. The latter is produced by dissolving bismuth in hot nitric acid. Addition of excess sodium hydroxide followed by continuous heating of the mixture precipitates bismuth trioxide as a heavy yellow powder. Also, the trioxide can be prepared by ignition of bismuth hydroxide. 

A white, microcrystalline powder, insoluble in water and in alcohol, but soluble in diluted hydrochloric, nitric, or sulphuric acid. On shaking bismuth subnitrate with water, it imparts an acid reaction to the latter. 

Chlorides. — On adding silver nitrate solution to a solution of 0.5 gm. of bismuth subnitrate in 5 cc. of nitric acid, not more than a slight opalescent turbidity should develop. 

Ammonia. — On warming 1 gm. of bismuth subnitrate with 10 cc. of sodium hydroxide solution (sp. gr. 1.3), no ammonia should he evolved (to be ascertained by moistened litmus paper). 

BASIC SALT. A compound belonging to the categories of both salts and bases, because it contains OH (hydroxyl) or O (oxide) as well as the usual positive and negative radicals of normal salts. Among the best examples are bismuth subnitrate, often written BiONO, and basic copper carbonate, Cu2 (OH)2CO.). Most basic salts arc insoluble in water and many arc of vaiiable composition.
