Addition of AgNO₃ to Aqueous Solutions of the Complex Results

question 36

Multiple Choice

Addition of AgNO₃ to aqueous solutions of the complex results in a cloudy white precipitate, presumably AgCl. You dissolve 0.1000 g of the complex in H₂O and perform a precipitation titration with 0.0500 M AgNO₃ as the titrant. Using an electrode that is sensitive to [Ag⁺], you reach the endpoint after 9.00 mL of titrant is added. How many grams of chloride ion were present in the 0.1000-g sample?

• A) 4.50  10^-4 g
• B) 1.77  10^-3 g
• C) 5.00  10^-3 g
• D) 1.60  10^-2 g
• E) 6.38  10^-2 g
