Electrode potentials for the half cells are shown below. Use the information to answer the questions that follow.
Sn2+(aq)+2e- Sn(s) ; = -0.14V
Cu2+(aq)+2e- Cu(s) ; = -0.34V

  1. Write the cell representation for the cell made up of two half cells. 
  2. Write the cell equation for the cell reaction. 
  3. Calculate the value for the cell.

  1. Write the cell representation for the cell made up of two half cells. 
    • Sn(s) /Sn2+(aq) //Cu2+(aq) /Cu(s) 
  2. Write the cell equation for the cell reaction.
    • Sn(s)+Cu2+(aq)→Cu(s)+Sn2+(aq)
  3. Calculate the value for the cell. 
    • Eθcell = Eθ reduced Eθ oxidation
      = +0.34 – ( -0.14)
      = +0.34++0.14
      = +0.48v
