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 250. mL sample of groundwater known to be contaminated with copper(II) chloride, which would react with silver nitrate solution like this: CuCl,(aq) + 2 AGNO3(aq) 2 AgCl(s) + Cu(NO,),(aq) The chemist adds 68.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 4.3 mg of silver chloride. Calculate the concentration of copper(II) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits. mg

![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 250. mL sample of groundwater known to be contaminated with copper(II) chloride, which would react with
silver nitrate solution like this:
CuCl,(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cu(NO,),(aq)
The chemist adds 68.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the
precipitate. He finds he has collected 4.3 mg of silver chloride.
Calculate the concentration of copper(II) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number
of significant digits.
