The standard reduction potentials of two half cells are;
Ag+(aq) + e  →  Ag(s) ; Eθ =+0.80v

Mg2+(aq) + 2e   → Mg(s) Eθ = −2.37

  1. Draw a well labelled diagram of an electrochemical cell that can be constructed using the two half cells.
  2. Determine the e.m.f of the above cell.

  1. Labelled diagram of Electrochemical cellusing half cells
  2. e.m.f = Eθred −  Eθoxide
            =+0.80 −(−2.37)
            =+3.17v
