When performing the "How Can the Identity of Metals be Determined?" investigation, copper (Eºred = 0.337V) was paired with unknown Metal IV to make a voltaic cell. First the potential was measured with red lead (cathode lead) attached to the copper, which read an Eº cell = -0.46 V. Next, the red and black leads were switched, and the black lead (anode lead) was attached to the copper, which read an Eºcell = +0.46 V. What is the Eºred for Metal IV? -0.797 V +0.797 V -0.123 V O +0.123 V
