A student is given a galvanic cell consisting of a zinc electrode and a copper electrode. If the concentration of zinc ions in the zinc half-cell is 0.1 M and the concentration of copper ions in the copper half-cell is 1.0 M, what is the corrosion potential of the zinc electrode at standard conditions? (Assume that the standard electrode potential of copper is +0.34 V and that of zinc is -0.76 V.)
