Step 1: Determine the concentration of Cn2-.

What is the minimum concentration of CN- (AT EQUILIBRIUM) that will prevent the precipitation of AgX(s) from a solution that is 0.149 M in X-(aq) and 0.0184 M in Ag+(aq)? (Ksp for AgX(s) = 5.2 ! 10-17; Kf for Ag(CN)2- = 5.6 ! 1018) 9.6 ! 10-3 M 9.4 ! 10-6 M 1.2 ! 10-3 M 3.1 ! 10-3 M 1.8 ! 10-10 M
