Answer to Question #56945 in General Chemistry for jgore

Question

A solution is made by mixing 500.0 mL of 4.0 M NH3 and 500.0 mL of 0.50 M AgNO3. Ag+ reacts with NH3 to form AgNH3+ and Ag(NH3)2+ according to the equilibrium reactions:

Ag+ + NH3 ↔ AgNH3+ K¬1 = 2.1 x 103

AgNH3+ + NH3 ↔ Ag(NH3)2+ K¬2 = 8.2 x 103

Assuming no change in volume on mixing calculate the concentrations of all species in solution: [Ag+], [NO3-], [NH3], [AgNH3+] and [Ag(NH3)2+].
