Question

Oo O CHEMICAL REACTIONS solving for a reactant in solution Favorites One way the U.S. Environmental Protection Agency (EPA) tests for chloride Any chloride anions in solution will combine with the silver cations to produce bright Suppose an EPA chemist tests a 200. mL. sample of groundwater known to be contaminated with copper(t) chioride, which would react with sive nitrate solution like this: CuCI 2(aq) + 2 AgNO3(aq) 2 AgCl (s) + Cu(NO3)2(aq) The chemist adds 59.0 mAf silver nitrate solution to the sample until siver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 7.6 mg of silver chloride. Calculate the concentration of coppert1) chioride contaminant in the original groundwater sample. Round your answer to 2
