Bromine mononitrate is an inorganic compound, derived from bromine and nitric acid with the chemical formula BrNO 3. The compound is a yellow liquid, decomposes at temperatures above 0 °C. [1] This compounds is extremely reactive due to its intrinsic instability, which makes handling and synthesis challenging.
Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst. However, reduction of bromine with red phosphorus is a more practical way to produce hydrogen bromide in the laboratory: [2] 2 P + 6 H 2 O + 3 Br 2 → 6 HBr + 2 H 3 PO 3 H 3 PO 3 + H 2 O + Br 2 → 2 HBr + H 3 PO 4
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).

Bromine addition to alkene reaction mechanism. An old qualitative test for the presence of the alkene functional group is that alkenes turn brown aqueous bromine solutions colourless, forming a bromohydrin with some of the dibromoalkane also produced. The reaction passes through a short-lived strongly electrophilic bromonium intermediate.
The agent used is sodium thiosulfate, and reacts according to the following equation: [2] AgX(s) + 2 Na 2 S 2 O 3 (aq) → Na 3 [Ag(S 2 O 3 ) 2 ](aq) + NaX(aq) An indefinite number of positive prints can be generated from the negative by passing light through it and undertaking the same steps outlined above.
Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
Bromine readily reacts with water, i.e. it undergoes hydrolysis: Br 2 + H 2 O → HOBr + HBr. This forms hypobromous acid (HOBr), and hydrobromic acid (HBr in water). The solution is called "bromine water". The hydrolysis of bromine is more favorable in the presence of base, for example sodium hydroxide: Br 2 + NaOH → NaOBr + NaBr
