A series of experiments was carried out in order to work out an activity series for some metals. Different metals were added to solutions of salts and the following experimental data were obtained: Metal Salt solution Observations I zinc copper(II) sulfate 11 zinc lead(II) nitrate brown deposit formed and the blue colour of the solution fades grey crystals formed on the piece of zinc III copper lead(II) nitrate no reaction IV zinc magnesium nitrate no reaction Identity and Explain which of the four metals is the strongest reducing agent. b. The chemistry of corrosion of iron is essentially an electrochemical phenomenon. Explain the reactions occurring during the corrosion of iron in the atmosphere. Provide chemical equation to your explanation. c. A galvanic cell is fabricated by connecting two half-cells with a salt bridge, one in which a chromium wire is immersed in a 1 M CrCl3 solution and another in which a copper wire is immersed in 1 M CuCl₂. Assuming the chromium wire functions as an anode, write the schematic for this cell along with equations for the anode half-reaction, the cathode half-reaction, and the overall cell reaction.
