2. Write the standard cell notation for the voltaic cells formed by the redox couples given below and calculate the Eᵒcell: a. . Zn(s) in ZnSO4(aq) and Cr(s) in CrSO4(aq) E°(Zn²+/Zn) = -0.76 V, Eº(Cr²+/Cr) = -0.91 V. b. Sn(s) in Sn²+ (aq) and Fe³+ (aq), Fe²+ (aq) E°(Sn²+/Sn) = -0.14 V, E°(Fe³+/Fe²=) = +0.77 V. c. Cu(s) in Cu²+ (aq) and Al in Al³+ (aq) E°(Cu²+/Cu) =+0.34 V, E°(A1³+/Al=) = -1.66 V. d. Co³+ (aq), Co²+ (aq) and Br₂Aq), Br¯ E°(CO³+/CO²+) =+1.82 V, E°(Br₂/Br¯) = +1.06 V.
