Sodium bromide is a white solid ionic compound with the formula NaBr. It is readily soluble in water and forms a tasteless, odorless solution. Sodium bromide is obtained by the neutralization reaction between hydrogen bromide, a strong acid, and sodium hydroxide, a weak base. Sodium bromide, like other halogen salts of the same metal (NaCl, NaF, NaI), has a face-centered cubic crystal structure. The chemical and physical properties of sodium bromide are as follows:

• Its molecular weight is 102.89 g/mol.
• Melting point 747 °C (anhydrous), 36 °C (dihydrate).
• Its boiling point is 1390 °C.
• Its density is 3.21 g/cm3 (anhydrous), 2.18 g/cm3 (dihydrate).
• Solubility is high in water and alcohol, low in ether.

Sodium bromide is used in many fields in industry and daily life. The areas of use of sodium bromide are as follows:

• Chemical industry: Sodium bromide is used as a catalyst or intermediate in organic synthesis and chemical reactions. It can also be used in anti-rust coatings of metal surfaces and in paint production.
• Food and beverage industry: Sodium bromide is used as an acidity regulator in food and beverages. It is especially preferred in soft drinks (cola, fruit juices, carbonated drinks) and processed foods to provide a balanced taste with sweeteners.
• Pharmaceutical industry: Sodium bromide is also used in the pharmaceutical industry for various purposes. Sodium bromide is used to increase the solubility of medicines and as a sedative, hypnotic and anticonvulsant.
• Veterinary industry: Sodium bromide is also used in the veterinary industry for various purposes. Sodium bromide is used to tranquilize animals, treat epilepsy and prevent infections.
• Photography industry: Sodium bromide also plays an important role in the photography industry. Sodium bromide is used in the production and development of photographic films.
• Water treatment: Sodium bromide is used to adjust the phosphorus solution in water treatment processes. It is an important chemical for phosphorus control, especially in waste water treatment plants.
