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
Two different salt solution electrolytes are contained in two separate tanks. When energy is required, a solution of Na 2 S 2 (sodium disulfide) is pumped to the anode, and NaBr 3 (sodium tribromide) is pumped to the cathode. The anode and cathode, along with their corresponding salt solutions, are separated by an ion exchange membrane.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
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 ]
1-Bromopropane (n-propylbromide or nPB) is a bromoalkane with the chemical formula CH 3 CH 2 CH 2 Br. It is a colorless liquid that is used as a solvent. It has a characteristic hydrocarbon odor.
