Dihydrate salt (NaBr·2H 2 O) crystallize out of water solution below 50.7 °C. [8] NaBr is produced by treating sodium hydroxide with hydrogen bromide. Sodium bromide can be used as a source of the chemical element bromine. This can be accomplished by treating an aqueous solution of NaBr with chlorine gas: 2 NaBr + Cl 2 → Br 2 + 2 NaCl
The classic case is sodium bromide, which fully dissociates in water: NaBr → Na + + Br −. Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with water to give an ionic solution called hydrobromic acid. The process is often described simplistically as involving formation of the hydronium salt of bromide:

The least stable, LiNO 3 (m.p. 255 °C (491 °F)) decomposes only at 474 °C (885 °F). At the other extreme, cesium nitrate melts at 414 °C (777 °F) and decomposes at 584 °C. [2] 60:40 mixture of sodium nitrate and potassium nitrate is a liquid between 260–550 °C (500–1,022 °F).

These may be metal salts containing bromide ion such as potassium bromide, or more covalent bromides of metals or nonmetals such as tantalum(V) bromide or phosphorus tribromide. See also [ edit ]
The polysulfide–bromine battery (PSB; sometimes polysulphide–polybromide or "bromine–sulfur") is a type of rechargeable electric battery that stores electrical energy in liquids, such as water-based solutions of two salts: sodium bromide and sodium polysulfide. It is a type of redox (reduction–oxidation) flow battery.
