Standard reduction potential (E) for reduction of CT_+2) O 7*2- to Cr 3+ is 1.232 V, in acidic medium. 2 If metal rod of Zn, Fe. Au and Ag is provided to you, which metal rod you wouldn't prefer for a spontaneous reduction of CL, O, to Cr in acidic medium. The reduction reactions and standard reduction potential values for Zn. Fe. Au and Ag are as follows: 3 Zn 2+ (aq) + 2e - Zn(s) E deg = -0.7618V 4 Fe 3+ (aq) +3e - Fe(s) E deg = - 0.03V B A u (aq) +le - Au(s) E deg 6 = 1692V A g (aq) +le - Ag(s) E deg = 0.7996V
