Sodium bromide CAS No.7647-15-6

Sodium bromide is an inorganic compound. It is a white crystal or crystalline powder that is soluble in water and has a bitter and salty taste. The following is an introduction to the properties, uses, preparation methods, and safety information of sodium bromide:

nature:

1. Sodium bromide is a strongly alkaline compound that can decompose with water to produce hydrobromic acid and sodium hydroxide.

2. Has a certain solubility, which increases with temperature.

3. Has antioxidant properties and can be used as an antioxidant.

4. At high temperatures, sodium bromide can react with silver chloride to produce bromine gas.

Purpose:

1. Sodium bromide is mainly used for the preparation of other bromides or as an analytical reagent.

2. It can also be used to prepare photosensitive materials such as photosensitive paper and photographic film.

Manufacturing method:

1. Usually, sodium bromide can be obtained by reacting magnesium bromide with sodium chloride.

2. In industry, sodium bromide can also be prepared by reacting bromine gas with sodium carbonate.

Security information:

1. Sodium bromide is a corrosive substance and can cause irritation when in contact with the skin and eyes. Direct contact should be avoided.

2. Attention should be paid to protective measures when using, such as wearing gloves and goggles, and maintaining good ventilation.

3. When storing, sodium bromide should be placed in a dry, non flammable place, away from flammable materials and oxidants.

4. When dealing with waste or spills, proper disposal should be carried out according to local regulations and guidelines.
