One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride
anions in solution will combine with the silver cations to produce bright white silver chloride precipitate.
Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with iron(III) chloride, which would react with silver nitrate solution
like this:
FeCl3(aq) + 3 AgNO3(aq)
3 AgCl(s) +
Fe(NO3),(a9)
The chemist adds 56.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds
she has collected 2.8 mg of silver chloride.
Calculate the concentration of iron(III) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant
digits.
