3. A student constructs a galvanic cell that has a strip of iron metal immersed in a solution of 0.1M Fe(NO3)2 as one half-cell and a strip of zinc metal immersed in a solution of 0.1M Zn(NO3)a as the other half-cell. The measured cell potential is less than zero when the positive terminal of the voltmeter is attached to the zinc strip and the negative terminal is attached to the iron strip. Which half-cell is the anode (Fe or Zn)? ade Which half-cell is the cathode? Do the electrons flow from Zn to Fe or Fe to Zn?
