Sodium bromide, represented by the chemical formula NaBr, is an ionic compound made up of sodium ions (Na⁺) and bromide ions (Br⁻). It is a white, crystalline solid that is highly soluble in water. Sodium bromide is commonly used in various applications, including pharmaceuticals, photography, and as a sedative in medicine. In addition to its industrial uses, NaBr plays a role in the production of bromine and other bromine compounds. It is also utilized in water treatment processes and as a source of bromide ions in chemical reactions. Safety precautions are necessary when handling sodium bromide, as it can be harmful in large quantities.
