Answer to Question #286337 in Physical Chemistry for Caldana

Question

Topic: Electrode Potential and Electrochemical Cells

Question 2

several different electrochemical cells can be constructed using the materials listed below.

1.0 M solution of AI(NO₃)₃, Fe(NO₃)₂ and Cu(NO₃)₂

metal strips of Al, Cu and Fe

salt bridge material and solution

• Cathode (Reduction) Haf-Reaction Al⁺³ (aq) + 3e^- —> AI(s) , Standard Potential E^o (volts) -1.66.

• Cathode ( Reduction) Half-Reaction Fe²⁺ (aq) + 2e^- —> Fe(s) , Standard Potential E^o (Volts) -0.41.
  
• Cu²⁺ (aq) + 2e^- —> Cu(s) , Standard Potential E^o (volts) +0.34.

a) write the balanced ionic equation for the reaction that occurs in the cell that would have the greatest positive value of E_cell (1 mark)

b) Calculate the standard cell potential E^o_cell for the reaction written in part (a). ( 2 marks)
