Answer Cr, Sn, Cu, Co, Cd is wrong.
Standard (reduction) potentials are given below for several half-reactions. Use them to answer the following. Mn2+(aq) + 2 е > Mn(s) Ered = -1.185 V Ered Cr3+(ag) + 3е > Cr(s) = -0.744 V Ered Sn2 (aq)2 e = -0.138 V Sn(s) Ered Cu2+(aq) 2 e » Cu(s) = +0.342 V Ered AI3+(aq) + 3 е > = -1.662 V Al(s) Ered =-0.280 v Со2+(aq) + 2 е > Co(s) Cd2+(aq)2 e...
