If a solution of silver nitrate, AgNO3, is added to a second solution containing a chloride, bromide, or iodide,
the silver ion from the first solution will precipitate the halide as silver chloride, silver bromide, or silver iodide.
If excess AgNO3(aq) is added to a mixture of the above halides, it will precipitate them both, or all, as the case
may be. A solution contains 1.73 g KCI and 1.87 g KBr. What is the smallest quantity of AgNO3 that is
required to precipitate both halides completely?
