Problem

Aqueous

\text{Ag}^+

ions react with

\text{Cl}^-

ions to form solid

\text{AgCl}

according to

\text{Ag}^+(aq)+\text{Cl}^-(aq)\rightarrow\text{AgCl}(s)

. A snapshot of the solution shows 15

\text{Ag}^+

ions and 12

\text{Cl}^-

ions. (i) Determine the number of

\text{AgCl}

formula units that precipitate. (ii) Identify and quantify any ions that remain in solution once precipitation is complete.
