A solution contains 0.0500 M Co^3+ (aq), 0.0290 M S^2–(aq), and 1.65 M NH3. Cobalt(III) ions in aqueous solutions complex with NH3 to produce Co(NH3)6^(3+) . (Kf = 5.0 x 10^31) What will be the concentration of Co3 (aq) when Co(NH3)6^3+ forms? Will Co2S3 precipitate? (Ksp = 4.0 x 10–21)

You have synthesized a redox reagent that is a complex between cobalt and six ammonia molecules ([Co(NH3)6] 3+/2+). It cycles between the Co(II) and Co(III) oxidation states. Unfortunately, after you complete your synthesis, you learn that your potentiostat is broken and you have no way to measure the reduction potential of your compound. Fortunately, you realize that you have sufficient information from other experiments and from data tables to determine the potential for this reagent. This information is: The standard...
