Answer to Question #52868 in General Chemistry for tiara

Question

. At STP, a galvanic cell was set up having the following half-reactions.
Fe2+(aq) + 2e- → Fe(s) -0.41
Cu2+(aq) + 2e-→ Cu(s) 0.34

The copper half-cell contained 100.0 mL of 1.00 M CuSO4, The lead half-cell contained 50.0 mL of 0.100 M FeSO4, to which was added 50.0 mL of 0.300 M NaOH. The cell potential was measured to be 1.155 V. What is the concentration of Fe2+ in the iron half-cell?
