Sodium bromide

It is a high-melting white, crystalline solid that resembles sodium chloride.

[7] NaBr crystallizes in the same cubic motif as NaCl, NaF and NaI.

[8] NaBr is produced by treating sodium hydroxide with hydrogen bromide.

Sodium bromide is used in conjunction with chlorine as a disinfectant for hot tubs and swimming pools.

Because of its high solubility in water (943.2 g/L or 9.16 mol/L, at 25 °C) sodium bromide is used to prepare dense drilling fluids used in oil wells to compensate a possible overpressure arising in the fluid column and to counteract the associated trend to blow out.
