Aqueous silver nitrate (AgNO₃) and aqueous sodium bromide (NaBr) react to produce solid silver bromide (AgBr) and aqueous sodium nitrate (NaNO₃). The reaction that occurs is as follows: If the reaction was carried out, what would the mass of the precipitate tell you .

Amount of bromide ion present

Explanation:

The reaction of aqueous silver nitrate with sodium bromide could be a method of gravimetrically determining the concentration of the bromide ion present. It has been an old analytical technique in chemistry to determine the concentration of an ion by precipitating the ion using the appropriate precipitating agent and weighing the precipitate.

By determining the mass of the bromide ion reacted we could also discover the amount of sodium bromide that originally reacted.
