You have an aqueous solution containing one or more of the following anions CO3*, cr, r and SO4. When you add Ba(NO)3(aq) you get a precipitate. You separate the precipitate (A) from the supernatant (B). To the precipitate (A), you add HCI(aq) and the solution fizzes and produces a colorless, odorless gas. To the supernatant (B), you add Ag(NO)3 and there is no reaction. Identify which ions are present, might be present, or are not present Co32- A. present B. not present CI C. might be present Soą2-
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 cadmium chloride, which would react with silver nitrate solution like this: CdCl2(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Cd (NO3)2(aq) The chemist adds 89.0 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 5.4 mg of silver chloride. Calculate the concentration of cadmium chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits. E d OL E
