Main Uses:

 

At room temperature, sodium bromide is a colorless cubic crystal or white granular powder, belonging to the equiaxed crystal system, odorless, with a slightly bitter taste, and highly toxic. It is easy to absorb moisture and clump in the air, but it does not deliquescence. It is slightly soluble in alcohol and easily soluble in water (with a solubility of 121g in 100ml of water at 100 ºC). Its aqueous solution is neutral and conductive. At 51 ºC, anhydrous sodium bromide crystals precipitate in the solution, while below 51 ºC, dihydrate is formed. Its bromide ion can be replaced by fluorine and chlorine. Under acidic conditions, it can be oxidized by oxygen to free bromine, which is utilized in industry to produce bromine. Can react with dilute sulfuric acid to generate hydrogen bromide. But hydrobromic acid is a strong acid and cannot be produced by reacting with dilute sulfuric acid. Only high boiling point acids can be used to produce low boiling point acids, but concentrated sulfuric acid cannot be used because concentrated sulfuric acid has strong oxidizing properties and will oxidize -1 valent bromine to elemental bromine, releasing a reddish brown gas. This method can be used to identify sodium iodide (sodium iodide and concentrated sulfuric acid are heated, releasing a purple red gas), so only concentrated phosphoric acid and sodium bromide can be used to produce hydrogen bromide by solid heating. Bromine ions can enhance the inhibitory process of the cerebral cortex and promote its concentration. Medically, it can be used as a sedative, hypnotic, or anticonvulsant. When a person swallows or inhales this compound, it can cause damage to the central nervous system, brain, and eyes, as well as irritating reactions to the skin, eyes, and respiratory tract.



A. Industrial use
Sodium bromide has various applications in industry:
1. Photographic industry: used for manufacturing photosensitive materials and photographic paper plates.
2. Spice industry: used for preparing spices.
3. Printing and dyeing industry: used for certain chemical reactions in the printing and dyeing process.
4. Disinfectant: Sodium bromide combined with chlorine can effectively control the growth of microorganisms in swimming pools and spas.
5. Photography: In the photography industry, sodium bromide is used to prepare silver bromide emulsions, which are an important component of traditional black and white film and printing paper.

B. Medical use and function
Sodium bromide also has multiple uses and functions in medicine:
1. Diuresis: By inhibiting the reabsorption of water and electrolytes by renal tubules, it can increase urine secretion and alleviate edema, urinary retention and other symptoms.
2. Sedation: It has a central nervous system inhibitory effect, reduces the excitability of the nervous system, and alleviates symptoms such as anxiety and insomnia.
3. Anesthesia: Enhance the efficacy of general anesthetics, reduce side effects, and improve anesthesia effectiveness.
4. Treatment of hypertension: dilate peripheral vascular smooth muscle cells, reduce peripheral resistance, and thus lower blood pressure.
5. Prevention of angina pectoris: Relaxing coronary artery smooth muscle cells, improving heart blood supply, and preventing the occurrence of angina pectoris.
6. Antiepileptic: Stabilize cell membrane potential, prevent abnormal discharge, and prevent epileptic seizures.
7. Hypnosis: Increasing chloride ion influx mediated by gamma aminobutyric acid (GABA) receptors to induce sleep state.
8. Muscle relaxation: affects postsynaptic membrane function, reduces neurotransmitter release, and leads to weakened or paralyzed muscle contraction.
9. Coughing: Reduce the sensitivity of respiratory mucosa and reflex cough, alleviate asthma symptoms
