Answer 1

NaBr, also known as sodium bromide, is an inorganic compound with the chemical formula NaBr. It is a white, crystalline solid that is highly soluble in water. NaBr is commonly used in various applications, including as a sedative, in the preparation of photographic films, and in the oil and gas industry.

Physical and Chemical Properties:

- NaBr has a molar mass of approximately 102.89 grams per mole. - It has a melting point of 755 degrees Celsius and a boiling point of 1,390 degrees Celsius. - NaBr is soluble in water, alcohol, and acetone. - It is a stable compound and does not readily decompose under normal conditions. - NaBr is an ionic compound, consisting of sodium cations (Na+) and bromide anions (Br-).

Uses of NaBr:

1. Medical Applications: NaBr has been used historically as a sedative and anticonvulsant. However, its medical use has declined due to the availability of more effective drugs. 2. Photography: NaBr is used in the preparation of photographic films. It is added to the emulsion layer of the film to increase its sensitivity to light. 3. Oil and Gas Industry: NaBr is used as a completion fluid in oil and gas wells. It helps control the pressure and prevent the collapse of the wellbore during drilling operations. 4. Chemical Synthesis: NaBr is used as a source of bromide ions in various chemical reactions. It can be used to prepare other bromine compounds or as a catalyst in certain reactions.

Safety Considerations:

- NaBr is generally considered to be low in toxicity. However, it can cause irritation to the skin, eyes, and respiratory system. - It is important to handle NaBr with care and follow appropriate safety precautions, such as wearing protective gloves and goggles. - Ingestion or inhalation of large amounts of NaBr can be harmful and may require medical attention.
