Use the standard reduction potentials shown here to answer the questions. > View Avallable Hint(s) Reduction hal-reaction E (V) (Cu**] = 2x10-14 M Cu" (aq) + 2e-Cu(s) 0.337 2H (aq) + 2e-H2(g) 0.000 Previous Answers Correct Because of the logarithm function, this answer actually has just one significant figure. It is expressed here with three significant figures because it will be used in the calculation for Part B. Part B Based on these data, what is the value of the formation constant, Ke , of (Cu(NH,)4* ? Express the formation constant numerically using one significant figure.

Use the standard reduction potentials shown here to answer the questions. A copper, Cu(s), electrode is immersed in a solution that is 1.00 M in ammonia, NH3, and 1.00 M in tetraamminecopper(). [Cu(NH3)4.If a standard hydrogen electrode is used as the cathode, the cel potential, Ecell, is found to be 0.066 V at 298 K. Reduction hal-reaction E (V) Cu" (aq) + 2e-Cu(s) 0.337 2H (aq) + 2e-+H2(g) 0.000 Part A Based on the cell potential, what is the concentration of Cu in this solution? Express your answer to one significant figure and include the appropriate units. > View Available Hint(s) (Cu*") - 2x10-14 M Rutm Prevlous Answers v Correct Because of the logarithm function, this answer actually has just one significant figure.
