The bromide ion concentration in a solution may be determined by the precipitation of silver bromide.
Ag+(aq) + Br (aq) —AgBr(s)
A student finds that 21.18 mL of 0.7650 M silver nitrate is needed to precipitate all of the bromide ion in a 50.00-mL sample of an unknown. What is the molarity of the
bromide ion in the student's unknown?
