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 iron(III) chloride, which would react with silver nitrate solution like this: FeCl3 (aq) + 3AgNO3 (aq) → 3AgCl (s) + FeNO33 (aq)The chemist adds 86.0m M silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 7.5mg 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.
Solid copper can be produced by passing gaseous ammonia over solid copper (II) oxide at high temperatures, according to the following reaction. NH3 (g) + CuO (s) → N2 (g) + Cu (s) + H2O (g) Balance the reaction.

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) + 3AgNO3 (aq) →3AgCl (s) + (FeNO3)3 (aq) The chemist adds 48.0mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 7.5mg of silver chloride.

When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate orcome apart. The resulting dissolved ions are electrically charged particles that allow the solution toconduct electricity. The following chemical equations represent this phenomenon:NaCl (s) → Na+ (aq) + Cl-(aq)Na2CO3 (s) → 2Na+(aq) + CO32- (aq)Write a similar balanced chemical equation for the other four strong electrolytes in the data table NaHCO3 KNO3NH4Cl HCl
