Question

A solution containing FeCl2 and FeCl3 is poured into one beaker containing an iron electrode while a solution containing Cd(NO3)2 is poured into another breaker containing an Cadium electrode. A salt bridge, NaNO3, is used to join the beakers. A wire passes through a voltmeter connects the electrodes. Answer the following.

A) polarity of the anode and cathode, indicate the direction of electron movement, direction of each ion migration

B) Write the half reactions and overall reaction. Determine Ecell(knot)

C) What is the potential of the cell, Ecell, under these conditions: [Cd(NO3)2]= 0.20M, [FeCl2= 0.20M], [FeCl3]= 4.0M
