When determining the relative reduction potentials of several electrode systems, why does it not matter what is chosen as a reference electrode? What action(s) is/are required to compare electrode potentials measured relative to different references? A galvanic cell is created according to the following cell notation: Al(s) | Al3+(1.0M) || Cu2+(1.0M) | Cu(s) Reduction Half Reaction E ̊ (volts) Al3+(aq) + 3e- -> Al(s) -1.66 Cu2+(aq) + 2e- -> Cu(s) 0.34 What is the overall cell potential? What would be...

Standard reduction potentials for nickel(II) and copper(II) The standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. The more positive the reduction potential, the more easily the substance gains electrons. Consider the following: Ni2+(aq)+2e−→Ni(s),Cu2+(aq)+2e−→Cu(s), E∘red=−0.230 V E∘red=+0.337 V What is the standard potential, E∘cell, for this galvanic cell? Use the given standard reduction potentials in your calculation as appropriate. Express your answer to three decimal places and include the...

Standard potentials are measured against the standard hydrogen electrode (S.H.E.). Because it is not always convenient to use a S.Н.Е., often other reference electrodes are used. The saturated calomel electrode (S.CE) is one commonly used reference electrode, with a reduction potential of +0.242 V versus the S.H.E. Using a table of standard reductions, determine what the standard reduction potential of each reduction half-reaction would be versus the S.C.E Cu2 +(aq) + 2 e-→ Cu(s) E* Al3 +(aq) + 3 e-→...
