You mix a solution of an unknown ionic compound with 10 mL of a 0.5 M solution of silver nitrate. The resulting mixture forms a grayish-white precipitate immediately upon mixing. You dry and weigh the solid, and find that it has a mass of 716.6 mg. Which of the following is the unknown solution? Write a balanced chemical equation for the resulting reaction. a. 5 mL of 0.5 M sodium acetate b. 10 mL of 0.5 M lithium bromide c. 15 mL of 0.8 M ammonium chloride
