When sodium bromide (NaBr) is put into water, it dissolves and dissociates into its ions:

NaBr(s) → Na+(aq) + Br-(aq)

Here's what this means:

* NaBr(s): Sodium bromide in its solid state.

* Na+(aq): Sodium ions dissolved in water. The (aq) indicates that the ion is surrounded by water molecules.

* Br-(aq): Bromide ions dissolved in water.

Key points:

* Sodium bromide is a soluble ionic compound. This means it readily dissolves in water.

* The process of dissolving is endothermic, meaning it absorbs heat from the surroundings.

* The dissolution of sodium bromide creates a neutral solution. This is because the sodium and bromide ions do not react with water to form acids or bases.
