Question

A half-cell that consists of a copper wire in 1.00 M CuNO3 solution is connected by a salt bridge to a half cell containing a 1.00 M X(II) acetate solution and an electrode of metal X. The voltage of the cell is 0.74 V, with metal X as the positive electrode. Calculate the standard reduction potential for the X half-reaction. The standard reduction potential of the copper half-reaction is 0.52 V. (Hint, write the half-reactions and the overall chemical equation for the spontaneous reaction.)

Explanation / Answer

THIS WILL BE HELPFUL FOR YOU

This is how I would figure it out: let me know if anything is unclear, I'll be sure to try and fix it up.

Okay:

Find the half cell reaction

CuI + e- => Cu + I- (at the anode)

Cu+ + e- => Cu (at the cathode) - SRP = + 0.52V

E
