Salt Bridge 2. Cu metal Zn metal Cu2+ 1.0 M Zn2+ 1.OM Answer the following questions about the setup and operation of a galvanic cell. a) One item is missing from this electrochemical cell that prevents it from functioning. Identify that item by drawing it onto the diagram. Label the missing item. b) Once this cell is operating, a redox reaction occurs. i) Which electrode, Cu or Zn, is the cathode? Explain. ii) Write the reaction for the half-cell containing zinc. iii) Calculate the voltage Eº for this cell. c) Set up the equation to calculate E in volts for the cell when the molarity of Cu2+ in the left half-cell is reduced to 0.10 M. Assume standard temperature. Label each factor in the equation with proper units. d) Suppose that the temperature of the original galvanic cell is decreased (from standard temperature) to 273 K. Would the voltage decrease, stay the same, or increase? Explain. e) What would be the effect on the voltage if the metal electrodes were doubled in mass? Explain. f) What would be the effect on the voltage if a solution of NaOH were poured into the Zn/Zn2+ half- cell? Explain. g) What would be the effect on the voltage if a solution of 10.0 M Zn(NO3)2 were poured into the Zn/Zn²+ half-cell? Explain.
