Consider three complexes of Ag⁺ and their formation constants, K_f.

Which statements are true?

(a) Ag(NH₃)₂⁺ is more stable than Ag(CN)₂^–.

(b) Adding a strong acid (HNO₃) to a solution that is 0.010 M in Ag(NH₃)₂⁺ will tend to dissociate the complex ion into Ag⁺ and NH₄⁺.

(c) Adding a strong acid (HNO₃) to a solution that is 0.010 M in AgBr₂^– will tend to dissociate the complex ion into Ag⁺ and Br^–.

(d) To dissolve AgI, one can add either NaCN or HCN as a source of the cyanide ion. Fewer moles of NaCN would be required.

(e) Solution A is 0.10 M in Br^– and contains the complex ion AgBr₂^–. Solution B is 0.10 M in CN^– and contains the complex ion Ag(CN)₂^–.

Solution B will have more particles of complex ion per particle of Ag⁺ than solution A.
