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.

A mixture consisting of only chromium(II) chloride (CrCl2, 122.90 g/mol) and iron(III) chloride (FeCl3, 162.20 g/mol) weighs 2.3738 g. When the mixture is dissolved in water and an excess of silver acetate is added, all the chloride ions associated with the original mixture are precipitated as insoluble silver chloride (AgCl, 143.32 g/mol). The mass of the silver chloride is found to be 5.7101 g. Calculate the mass percentage of chromium(II) chloride in the original mixture.
