10) . Use the principles that you learned in Part ii tocalculate the standard reduction potentials for each half-cell,given that the EÂ° for Cu2+ + 2e- ïƒ Cu (s) is 0.34 V.Note that EÂ°for a half-reaction is not dependent on the coefficients, providedof course that the reaction is balanced, i.e., EÂ° for Ag+ + e-ïƒ Ag(s) is the same as EÂ° for Ag+ + 2e-ïƒ 2 Ag (s)

The Cu half cell is reference and what you measure is how much the potential of the other half cell is below the reference because these values are negative Measured emf EM2M ECu2Cu Thus EM2M measured emf ECu2Cu measured emf 034 V Now you may calculatebut I suppose your experimental procedure was each metal M in its half cell had the corresponding See Answer
