Question

Sketch the galvanic cells based on the following overall reactions. Calculate ϐo, show the direction of electron flow and the direction of ion migration through the salt bridge, identify the cathode and anode, and give the overall balanced equation. Assume that all concentrations are 1.0 M and that all partial pressures are 1.0 atm. Standard reduction potentials are found in Table 11.1.
a. Cr3+(aq) + Cl2(g) ⇌ Cr2O72-(aq) + Cl-(aq)
b. Cu2+(aq) + Mg(s) ⇌ Mg2+(aq) + Cu(s)
c. IO3-(aq) + Fe2+(aq) ⇌ Fe3+(aq) + I2(s)
d. Zn(s) + Ag+(aq) ⇌ Zn2+(aq) + Ag(s)
Table 11.1
