![EXERCISE IV- 1. (Complex Ion Equilibria)
1. If 25.00 mL of 0.100 M AgNO3 is mixed with 25.00 mL of 0.300 M NACN, find (Ag*], [Ag(CN)2],
and [CN]. Kf, Ag(CN), = 7.08 x 1019
2. How many moles of AgCls) will dissolve in 1.00 L of 0.100 M NACN? What are the concentrations
of the various ions?
3. A solution has an equilibrium NH4OH concentration of 0.800 M and a total dissolved silver
concentration of 0.100 M. What is the maximum [CI] that can be present without AgCls) forming?
Ksp AgCl = 1.82 x 1010, K1 Ag(NH3)2* = 2.0 x 10° , K2 Ag(NH3)2* = 1.6 x 107

4. If exactly 1.00 liter of 2.0 M NH3 (final concentration) is required to dissólve 5.0 mmol of the silver
salt, AgX, what is the Kgp of AgX ?
5. Calculate the solubility in g/100 mL of the AgI in 0.10 M NH3. The NH3 concer:tration is-that of
uncomplexed NH; at equilibrium. Ksp of AgI = 8.3 x 1017,
