Calculate the corrosion potential of a pure copper metal electrode immersed in a 0.1 M solution of CuSO4 at 298 K, given that the standard electrode potential of Cu2+/Cu is +0.34 V and the standard potential of the hydrogen electrode is 0 V. Assume that activity coefficients for copper ions and sulfate ions are equal to 1.0 in the solution. What is the likelihood that this copper electrode will corrode in this given environment?
