Assume the following half reactions: You have water-soluble iron(II)- and iron(III)- chloride salts, KCl, water, two beakers, a U-shaped tube, two platinum wires, two copper clips that can connect to and hold the platinum wires, agar (a gel), a silver wire coated with AgCl and voltmeter. (3) how you can make a voltage source out of (a subset or all of this. What is the standard potential difference you can get (3)? You can vary the actual voltage by changing some concentration. (2) Write the equation that governs these voltages. (2) Suggest ways to increase and decrease the voltage by means of concentrations.
