An electrolytic cell containing one half-cell consisting of a nickel electrode in a 1 mol/L nickel (III) chloride solution and the other half-cell consisting of a cadmium electrode in a 1 mol/L cadmium chloride solution is assembled.
(a) Sketch the cell and label the anode, the cathode, and the direction of electron flow. Be sure to include a salt bridge and a power supply in your sketch.
(b) Find the cell potential.
(c) Write the oxidation half-reaction, the reduction half-reaction and the overall cell reaction.
d) Explain how the electrolytic cell works.
Which of the following reactions occurs spontaneously and which can only be brought about through electrolysis, assuming that all reactants and products are in their standard states? For those requiring electrolysis what is the minimum voltage required?
(a) Zn(s) + Fe2+(aq) ? Zn2+(aq) + Fe(s)
(b) 2 Fe2+(aq) + I2(s) ?2 Fe3+(aq) + 2 I-(aq)
(C) Cu(s) + Sn4+(aq) ? Cu2+(aq) + Sn2+(aq)
