For each of the following redox reactions, sketch a diagram of a galvanic cell indicating the oxidation and reduction half-reactions, the anode, the cathode, the direction of electron flow in the wire and the direction of positive ion migration through the porous disk. Additionally, list the components of each half-cell. Assume each reaction proceeds in the forward direction as written.
For each of the calculate the cell potential, Eo cell, given the following brief table of standard reduction potentials.
a. 1.78 V + 2.90 V = 4.68 V
b. 1.00 V + 2.37 V = 3.37 V
c. 0.54 V + 0.23 V = 0.77 V
For each of the provide the line notation that describes each. Assume that all species are in their standard states.
a. Ba (s) | Ba2+ (aq) || H+ (aq),
H2O2 (aq) | Pt
b. Mg (s) | Mg2+ (aq) || H+ (aq), VO2 + (aq), VO2+ (aq) | Pt
c. Ni (s) | Ni2+ (aq) || I2 (aq), I- (aq) | Pt
