Pre-Laboratory Assignment (Use Table 1 as a source of half-equations and reduction potentials for this assignment.) 1. Rank the following metals by ease of oxidation, from hardest to easiest Cu; aluminum, Al; Fe; and chromium, Cr. 2. An Al strip is placed in CuSO4 solution. (1) Would you expect a spontaneous reaction to occur, based on the net potential? (2) If your answer to (1) is "yes," what would you observe? (3) Write a chemical equation that describes your predicted observations. 3. Describe what you would observe if you placed an Ag strip in an aluminum nitrate solution, Al(NO3)3. 4. Describe an electrochemical cell that would have the following net equation, by answering the following questions. Fe(s)+Ni2(aq)Ni(s)+Fe2(aq) (1) Write the reduction and oxidation half-equations for the cell. (2) Sketch the electrochemical cell. Identify the components of the cell as in Figure 1. (3) Calculate the expected net voltage for this cell
