Structure of Sodium Bromide:
Sodium is a positively charged radical that is highly volatile. The element reacts with the negatively charged bromide radical to form a predominantly stable ionic bond that forms the sodium bromide compound.
Sodium Bromide Production Process:
Sodium bromide can be prepared in several ways:
- From the reaction of sodium hydroxide with hydrogen bromide:
HBr + NaOH → NaBr + H2O
- From the reaction between the bromine solution and sodium hydroxide:
6NaOH + 3Br2 → 5NaBr + NaBrO3 + 3H2O
Sodium Bromide Uses:
- In medicine as an anticoagulant, anticonvulsant and sedative; like Trisodium citrate
- The main consumer of sodium bromide in the oil and gas drilling industry
- As a disinfectant, detergent, and as a reagent in the pharmaceutical industry
- As a catalyst in oxidation reactions
- In the preparation of liquid photography film as a raw material
- As a bromine agent in the printing and dyeing industry
- The perfume industry produces synthetic perfumes
