Calculate the equilibrium concentrations of NH3, Cu2+, [Cu(NH3)]2+, [Cu(NH3)2]2+, [Cu(NH3)3]2+, and [Cu(NH3)4]2+ in a solution made...

Calculate the equilibrium concentrations of NH3, Cu2+, [Cu(NH3)]2+, [Cu(NH3)2]2+, [Cu(NH3)3]2+, and [Cu(NH3)4]2+ in a solution made by mixing 500.0 mL of 3.00 M NH3 with 500.0 mL of 2.00 x 10-3 M Cu(NO3)2. The sequential equilibria are Cu2+ (aq) + NH3(aq) ⇐⇒ [Cu(NH3)]2+ (aq) K1 = 1.86 x 104 [Cu(NH3)]2+ (aq) + NH3(aq) ⇐⇒ [Cu(NH3)2]2+ (aq) K2 = 3.88 x 103 [Cu(NH3)2]2+ (aq) + NH3(aq) ⇐⇒ [Cu(NH3)3]2+ (aq) K3 = 1.00 x 103 [Cu(NH3)3]2+ (aq) + NH3(aq) ⇐⇒ [Cu(NH3)4]2+ (aq)...

Cu +2 OH --> Cu(OH)2 Cu+ 6 NH3 -->Cu(NH3)6 add drops of 6 m NH3 until a change is observed. a) what is happening at the molecular level when NH3 is added? How are the positions of equilibrium affected for both equations 1 and 2? explain. b) Add drops of 6 M HCl until a change is observed. stir the solution as you add HCL. What will you observe? c) what is happening at the molecular level when the HCl...

Choose the most likely pattern for the crystal field diagram for the complex trans–[Ni(NH3)2(CN)4]2– where CN– produces a much stronger crystal field than does NH3.? From the answer the pattern show it is a square planer. Could anyone explain it? why is not octahedral?
