Commercial silver-plating operations frequently use a solution containing the complex Ag(CN)2- ion. Because the formation constant (Kf) is quite large, this procedure ensures that the free Ag+ concentration in solution is low for uniform electrode position. In one process, a chemist added 9.0 L of 5.0 M NaCN to 90.0 L of 0.20 M AgNO3. Calculate the concentration of free Ag+ ions at equilibrium. See Table 16.4 for Kf value.
