The answer is 1. Why? Please show all your work cleanly. How many unpaired electrons would you expect for the complex ion: Co(NH3? 0 3 O 2 How many unpaired electrons would you expect for the complex ion: Co(NH3? 0 3 O 2
In acidic aqueous solution, the purple complex ion Co(NH3)5Br2+ undergoes a slow reaction in which the bromide ion is replaced by a water molecule, yielding the pinkish-orange complex ion : Co(NH3)5(H2O)3+ Co(NH3)5Br2+Purple(aq)+H2O(l)→ Co(NH3)5(H2O)3+Pinkish−orange(aq)+Br−(aq) The reaction is first order in Co(NH3)5Br2+, the rate constant at 25 ∘C is 6.3×10−6 s−1, and the initial concentration of Co(NH3)5Br2+ is 0.100 M. What is its molarity after a reaction time of 24.0 h ? How many hours are required for 77 %% of the...

The complex ion Cu(NH3)42+ is formed in a solution made of 0.0300 M Cu(NO3)2 and 0.400 M NH3. What are the concentrations of Cu2+, NH3, and Cu(NH3)42+ at equilibrium? The formation constant*, Kf, of Cu(NH3)42+ is 1.70 x 1013 Suppose you have a solution that contains 0.0440 M Ca2+ and 0.0980 M Ag+. If solid Na3PO4 is added to this mixture, which of the following phosphate species would precipitate out of solution first? When the second cation just starts to precipitate, what percentage...

Balance the following redox-reaction in a acid solution by using the ion-electron method ClO4-(aQ) + PO33-(aq) --> Cl2(aq) + PO43-(aq)
8. A 0.15 M aqueous of the chloride salt of the complex ion Pt(NH3)4 is found to be weakly acidic with a pH of 4.92. This is initially puzzling because the Cl ion in water is not acidic and the NH3 in water is basic, not acidic. Finally, it is suggested that the Pt(NH3)4 ion as a group donates protons. Compute the K, of this acid, assuming that just one hydrogen is donated.
