Electrode Potentials and Voltaic Cells

For each of the following;

  1. Write the overall cell reaction/ cell representation
  2. Calculate the standard cell potential (Eo)
  3. Determine whether the reaction is spontaneous or non-spontaneous.
    • Ca(s)  +  Cu+2(aq)  → Cu(s)  +  Ca+2(aq)
    • 2 Br-(aq)  +  Sn+2(aq)  → Br2(l)  +  Sn(s)
    • 2 Ag(s)  +  Ni+2(aq)  → 2 Ag+(aq)  +  Ni(s)
